"I advocate a high tolerance for the people who define themselves by their choice of a homosexual lifestyle, even while I promote a low tolerance for homosexual conduct." - In A Letter to the Lithuanian People
" In reality, homosexuality is nothing more than same-gender conduct among people who are innately and unchangeably heterosexual. Homosexuality is thus biologically (and to varying degrees morally) equivalent to pedophilia, sado-masochism, bestiality and many other forms of deviant behavior." - Deciphering 'gay' word-speak and language of confusion
"We Declare that the human rights of religious and moral people to protect family values is far superior to any claimed human right of those who practice homosexuality, and we Call for the European Union and the international community to immediately abandon any campaign to create a human right for homosexual conduct, and to restore religious freedom and family values to their proper superior status." - Riga Declaration on Religious Freedom, Family Values and Human Rights, authored by Scott Lively 
"Like Justice Robert Jackson and the jurists of two millennia, we reject the effort of self-serving people to choose their own morality in the face of revealed universal truth. And like modern environmentalists we can prophesy with assurance that removing social and legal protections for the natural family will have dire and long-lasting consequences for us all."
