In some regions where the secular left has considerable influence, they are losing an increasing amount of their power. For example, in secular Europe right-wing nationalist political parties are growing. In addition, religious conservatives are immigrating to secular Europe in significant numbers and having more children than their secular population which is expected to increase social conservatism in Europe over time (see: Desecularization).
Beliefs of the secular left
See also: Atheism and politics
1. They are actively opposed to any role of religion in politics or in government and so support the separation of church and state. Ironically, they are not in opposition to the religious left and don't challenge their religion yet do attack the right wing over religion..This was seen in Australia, Tony Abbott, a conservative Catholic was berated by the Secular Left present in Australia. Yet the secular left didn't condemn the Uniting Church minister from Queensland who stood as a left-wing minister.
2. They also believe in forming a secular state. This would involve a state being completely neutral to all forms of religion and having no legal stance with regard to religion. France is a secular state due to the policy of laïcité which is the strict separation of state from church. Despite the fact that 51% of the population are Catholic, there is no legal safeguard for the religion as religion is considered an entirely private matter.
3. The third main belief is that there should be Secular education. The idea of God or religion should not be in the classroom and, as such, classroom prayer should be illegal. In Georgia, their opposition could be seen when they wanted four teachers fired and 50 students to be disciplined for holding a “prayer rally” 
Secular left and opposition to religious conservatives
The Barna Group found regarding atheism and morality that those who hold to the worldviews of atheism or agnosticism in America were more likely, than theists in America, to look upon the following behaviors as morally acceptable: illegal drug use; excessive drinking; sexual relationships outside of marriage; abortion; cohabitating with someone of opposite sex outside of marriage; obscene language; gambling; pornography and obscene sexual behavior; and engaging in homosexuality/bisexuality.
History of the secular left
According to the University of Cambridge, historically, the "most notable spread of atheism was achieved through the success of the 1917 Russian Revolution, which brought the Marxist-Leninists to power." Vitalij Lazarʹevič Ginzburg, a Soviet physicist, wrote that the "Bolshevik communists were not merely atheists but, according to Lenin's terminology, militant atheists." However, prior to this, the Reign of Terror of the French Revolution established an atheist state, with the official ideology being the Cult of Reason; during this time thousands of believers were suppressed and executed by the guillotine.
Vladimir Lenin wrote: "A Marxist must be a materialist, i. e., an enemy of religion, but a dialectical materialist, i. e., one who treats the struggle against religion not in an abstract way, not on the basis of remote, purely theoretical, never varying preaching, but in a concrete way, on the basis of the class struggle which is going on in practice and is educating the masses more and better than anything else could."
Influence of the secular left in America
Theodore Beale wrote:
|“||The reason the Christian voices are so well-heard is that the Christian community is so large, a much larger "minority" than blacks, Jews or homosexuals. That's why the Left, for all its mantra of "democracy, democracy", fears the Religious Right and needs combat it through the courts instead of the ballot box. The secular Left is so unpopular and so numerically insignificant that it can't even win in the strictly limited democracy of the American political system and so is forced to have its "democracy" at a third remove, by unelected judges.||”|
In 2017, the American atheist PZ Myers, quoting fellow leftist Alex Nichols, wrote: "...the growing popularity of jibes associating outspoken atheists with fedoras, neckbeards, and virginity, led to an exodus of liberals and leftists from the “atheist” tent. Those who remained for the most part lacked in social skills and self-awareness, and the results were disastrous."
Secular left and mass murder
See also: Atheism and mass murder
Theodore Beale wrote about the secular left and mass murder:
|“|| ...it does, however, cast serious doubt on the common atheist assertion that a godless society will be a peaceful one. The significant question has never been if atheism causes political leaders to kill in large quantities, it is why political leaders who happen to be atheist have been inordinately inclined to kill in large quantities.
As I wrote in TIA, the answer is probably to be found in the fact that atheists who have committed great historical crimes are almost exclusively left-wing atheists with utopian visions of restructuring human society; Ayn Rand atheists aren't exactly known for attempting to violently restructure societal order. This is why atheists like Bertrand Russell, Sam Harris, Christopher Hitchens, and especially Michel Onfray are far more dangerous than those more akin to Daniel Dennett and even Richard Dawkins.
The degree to which atheist society is authoritarian vs. wedded to a democratic process also has a bearing on whether it will engage in mass murder.
Secular leftism and loss of economic productivity
Secular leftism does not lead to long term economic stability and productivity (see: Atheism and loss of economic productivity).
Widespread sloth in the former Soviet Union helped cause much poverty. A study performed in the former Soviet Union found that over 50% of the work force admitted to drinking alcohol while on the job (See also: Atheism and alcoholism).
On the other hand, Harvard University historian Niall Ferguson declared: "Through a mixture of hard work and thrift the Protestant societies of the North and West Atlantic achieved the most rapid economic growth in history." In China, the growth in religion has accompanied China's fast economic growth over the last twenty years. Christianity is seeing rapid growth in China and the historian Niall Ferguson attributes this recent economic growth to the Protestant work ethic being more incorporated into Chinese society. See also: Protestant work ethic and Growth of Christianity in China
Secular left, Soviet Union and historical revisionism
See also: Atheism and historical revisionism
In terms of academic and popular history, the Communist Party of the Soviet Union (CPSU) often engaged in historical revisionism via their control of political/ideological public discourse (media, education, etc.) and via the monitoring/silencing/imprisonment/persecution of citizens through the KGB.
See also: Atheism and socialism
The Acton Institute states concerning atheism and socialism:
|“|| ...a growing body of research reveals that as the welfare state grows, the church shrinks. Adam Kay of Duke University discovered that church and state have a “hydraulic relationship”: Events “that lower faith in one of these external systems (e.g., the government) lead to subsequent increases in faith in the other (e.g., God).” Another study found that increased welfare spending “in a specific year predicted lower religiosity one to two years later.” It concluded, “The power and order emanating from God can be outsourced to the government.”...
...faith in the transcendent gets crowded out by faith in socialism’s utopian promise of equality-of-outcome on earth. This path transformed Michael Harrington from a daily communicant volunteering in the Catholic Worker movement to the atheistic founder of the Democratic Socialists of America.
Leading American atheist organizations lean to the left politically
According to Republican Atheists' President Lauren Ell, the leading atheist organizations such as American Atheists, Freedom From Religion Foundation and Secular Student Alliance lean left politically.
Secular left vs. secular right
This has contributed to infighting within the atheist movement (see: Western atheism, schisms and political polarization and Atheist factions).
Secular leftism is declining in the 21st century
As noted above, historically the largest advances of the secular left has been through utilizing the power of the state (see: State atheism and Atheism and communism). For example, secular leftists use the power of the state to promote evolutionary ideology and to censor creationist/intelligent design models of origins (See: Suppression of alternatives to evolution and Atheist indoctrination).
|“|| In the Americas, the Trump tsunami has swept across both continents and the 'pink tide' of progressivism has all but disappeared from the southern half of the hemisphere...
In this planet-wide rising tide of right-wing populism, the liberal left commands only a few disconnected islands — Iceland, Mexico, New Zealand, South Korea, Spain, Uruguay... Worse, crafty operators with even more ambitious agendas stand ready to destroy the liberal status quo once and for all."
Although the secular left has made some significant recent gains in the culture war (for example, the legalization of homosexual marriages in many Western nations), the historian Martin Van Crevel points out that sovereign states are losing power/influence due to technology democratizing access to information, welfare states increasingly failing, fourth-generation warfare being waged against countries and sovereign states increasingly losing their ability to maintain internal order.
Professor Eric Kaufmann says about a graph showing the correlation between the projected growth of the Muslim propulation and the rise of right-wing nationalism in a country:
|“||Figure 1 shows an important relationship between projected Muslim population share in 2030 and support for the populist right across 16 countries in Western Europe. Having worked with IIASA World Population Program researchers who generated cohort-component projections of Europe’s Muslim population for Pew in 2011, I am confident their projections are the most accurate and rigorous available. I put this together with election and polling data for the main West European populist right parties using the highest vote share or polling result I could find. Note the striking 78 percent correlation (R2 of .61) between projected Muslim share in 2030, a measure of both the level and rate of change of the Muslim population, and the best national result each country’s populist right has attained."||”|
Samuel P. Huntington's thesis on the The Clash of Civilizations and the Remaking of World Order keeps getting vindicated.
In the United States, the secular left has lost significant ground in the culture war relating to abortion and many states are restricting access to abortion.
The Birkbeck College, University of London professor Eric Kaufman wrote in his 2010 book Shall the Righteous Inherit the Earth? concerning America:
|“||High evangelical fertility rates more than compensated for losses to liberal Protestant sects during the twentieth century. In recent decades, white secularism has surged, but Latino and Asian religious immigration has taken up the slack, keeping secularism at bay. Across denominations, the fertility advantage of religious fundamentalists of all colours is significant and growing. After 2020, their demographic weight will begin to tip the balance in the culture wars towards the conservative side, ramping up pressure on hot-button issues such as abortion. By the end of the century, three quarters of America may be pro-life. Their activism will leap over the borders of the 'Redeemer Nation' to evangelize the world. Already, the rise of the World Congress of Families has launched a global religious right, its arms stretching across the bloody lines of the War on Terror to embrace the entire Abrahamic family.||”|
Decline of the secular left and demography and religious immigration
See also: Global atheism
On December 23, 2012, Professor Eric Kaufmann who teaches at Birbeck College, University of London wrote:
|“|| I argue that 97% of the world's population growth is taking place in the developing world, where 95% of people are religious.
On the other hand, the secular West and East Asia has very low fertility and a rapidly aging population. The demographic disparity between the religious, growing global South and the aging, secular global North will peak around 2050. In the coming decades, the developed world's demand for workers to pay its pensions and work in its service sector will soar alongside the booming supply of young people in the third world. Ergo, we can expect significant immigration to the secular West which will import religious revival on the back of ethnic change. In addition, those with religious beliefs tend to have higher birth rates than the secular population, with fundamentalists having far larger families. The epicentre of these trends will be in immigration gateway cities like New York (a third white), Amsterdam (half Dutch), Los Angeles (28% white), and London, 45% white British. 
Kaufmann told a secular audience in Australia: "The trends that are happening worldwide inevitably in an age of globalization are going to affect us."
Decline of the secular left in Europe in the 21st century
See also: Desecularization and politics
Between the years of 2021 and 2050, a tipping point is expected to occur in Europe as a whole and then secularization will plateau followed by a long term trend of desecularization.
In June 2014, Forbes reported that it is undeniable that politically right wing parties are ascendant in Europe.
In 2010, Kaufmann reported that the rate of secularisation flattened to zero in most of Protestant Europe and France.
Secular left and Donald Trump's election
See also: Donald Trump and American atheists
The Religion News Service reported:
|“|| For the last decade, atheists, humanists and others secularists have worked hard to organize a “secular vote” that would counter the political clout of the religious right.
President-elect Donald J. Trump’s victory dealt that movement a body blow when he garnered 81 percent of the white evangelical vote and 60 percent of the white Catholic vote. Mormons, too, voted overwhelmingly for Trump.
Despite Trump’s not being a particularly religious person, his platform was seen as anti-secular in many atheist and humanist circles. He said he would appoint religiously conservative Supreme Court justices, ban Muslim immigrants, favor Christianity and repeal the Johnson Amendment, which prohibits certain tax-exempt organizations from endorsing political candidates — issues antithetical to organized atheism and humanism.
Ideological dogmatism of the secular left in Western World
In the Western World, the secular left has failed the learn the lessons of the collapse of the Soviet Union and the economic failures of Venezuela. A primary cause of the Soviet Union's collapse was its economic problems.
Atheist deification of politics

Progressive values according to leading progressive websites
According to leading progressive/leftists websites, progressive values include: freedom; opportunity; responsibility; cooperation/community; caring and responsibility, carried out with strength; protection/fairness; honesty and open communication.
Atheism and lack of cooperation/community
The atheist population lacks cooperation/community, is known for engaging in bitter quarrels and is deeply divided (see: Atheist factions and Atheist movement). It also has significant racial/gender issues (see: Western atheism and race and Atheism and women).
Atheism and lack of empathy
As far as the progressive values of caring/protection, the American atheist population gives less to charity per capita than Christians even when church giving is not counted (see: Atheism and uncharitableness).
In addition, the historical record shows that atheists have often been uncaring and atheists have engaged in barbarous/uncivilized behavior (see: Atheism and mass murder and Mass rape of German women by the Soviet army and Atheism and cannibalism and Atheism and bestiality).
Atheists falling short of the progressive value of freedom
Atheists and the issue of honesty
As far as honesty, atheists have a poor record in this area as well (see: Atheism and deception).
Atheism and liberal Christianity
Although liberal Christianity adherents disagree with secular leftists on various matters, they do with work with secular leftists on matters of agreement (see: Atheism and liberal Christianity alliances).
Secular leftists and terrorism
Secular left, humor and hypocrisy
See also: Atheism and humor
Although the secular left is known for ridiculing religion since at least the time of French Revolution (see: Atheism and mockery), the secular left is known for its humorlessness when it comes to others mocking of its ideology (See also: Atheism and humor and Atheism and intolerance).
Ex-atheist John C. Wright on American secular leftism being a religion
|“|| ...all the Progressives do is take their religion, Social Justice Marxism, or whatever name it is going by these days, and PRETEND it is not a religion at all, and they press their worldview as if it were the default worldview promoted by the Constitution and by the consensus of academia, and declare the burden of proof to be on the conservative to proof otherwise. And when the conservative does prove otherwise, the Progressive decrees from the bench that the proof is inadmissible, on the grounds that no religious arguments can be brought into the public sphere to argue against the Progressive religion. Because it is said to be not a religion, you see...
They were triumphant because they were and are a religion, not a political movement. In a religion, dogma is accepted on faith, by bowing to the authority of the prophets or the Church who speak God’s word. To question the faith is an act of immorality, of disloyalty, of subversion. Hence the Progressive has no need and no ability to defend his dogma: he merely condemns the questioner as a heretic, a man with bad motives...
The Progressive is fighting a holy war. A holy war concerns not one policy or one thing, but everything. It is a war to impose a worldview on the world. It cannot compromise.
Politics is merely one branch springing from the trunk of one’s worldview, and one’s worldview grows out of the roots of one’s religious background. Even atheists with a Christian background have their worldview so informed.
Facing holy warrior with prudential political arguments about policies and politics is bringing a knife to a gunfight.
Conservatism is insufficient, since it only addresses the political side of life. The Christian roots of conservativism alone have the strength to resist the attempt to undermine and uproot civilization.
Only a crusader can face a jihadist.
Wright wrote about secular leftist rioting and Islamic terrorism:
|“||The rioters and the terrorist have combined against us. Both use the same language of victimology, the same tactics of crybaby-bullies, who bludgeon girls from behind while weeping like brats that they are the wounded party. Both are utterly evil, and utterly blinded by their own self-righteousness. One is an open religion, the heresy of Mohammedanism. The other is a an agnostic and materialistic variant on the old, old heresy called Gnosticism, the belief that each man is his own god, and that God is a devil who must be reviled and overthrown.||”|

It is wonderful that, amid the horrors of this dismal period, while "the death dance of democratic revolution" was still in rapid movement, among the tears of affliction, and the cries of despair, "the masque, the song, the theatric scene, the buffoon laughter, went on as regularly as in the gay hour of festive peace."”
- William Kilpatrick (2012). Christianity, Islam, and Atheism: The Struggle for the Soul of the West. Ignatius Press.

The former led to the American Revolution, the Declaration of Independence, the abolition of slavery, and the civil rights movement. The latter led to the French Revolution, the Reign of Terror, the suppression of church by state, and the godless philosophies of Marx and Nietzsche and their offspring-National Socialism and communism. More recently the abandonment of God has led to the regime of cultural relativism that regards rights as arbitrary constructions. It's this second Enlightenment tradition that Cardinal Ratzinger referred to when he wrote, "The radical detachment of the Enlightenment philosophy from its roots ultimately leads it to dispense with man." Actually this transition happened no "ultimately" but almost immediately. The first instance occurred when Enlightenment worship of abstract "reason" and "liberty" degenearated quickly into the mass murders committed during the antireligious Reign of Terror in France. "Liberty, what crimes are committed in your name", said Madam Rolande as she faced the statue of Liberty in the Place de la Revolution movements before her death at the guillotine. She was one of the early victims of a succession of secular systems based on rootless notions of "liberty", "equality", and "reason". As many historians have pointed out, the atheist regimes of modern times are guilty of far more crimes than any committed in the name of religion. Communist governments alone were guilty of more than one hundred million murders, most of them committed against their own people.”
