Atheism is the disbelief in the existence of any supernatural deity. This disbelief can take a number of forms, such as the assertion that deities do not exist, or the absence of any belief in any deity.
Stalin and Richard Dawkins are prominent atheists. Dawkins wrote a book, called "The God Delusion". Stalin is now dead, having killed millions of people in the name of Marxis-Leninism (which is predicated on atheism). In contrast, neither Hitler nor Tomás de Torquemada were atheists; both are also now dead, having killed millions of people in the name of Christianity.
Since atheists have no God and therefore no grounds for a system of morality, they live their lives according to the rule that "anything goes".[Citation Needed] In recent years, this has led to a large rise in drug use, pre-marital sex, teenage pregnancy and pedophilia.[Citation Needed]
