Atheism and hedonism
The Barna Group found that atheists and agnostics 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. Given the many diseases associated with homosexuality, the biblical prohibition against homosexuality is quite arguably one of the many examples where the Bible exhibited knowledge that was ahead of its time.
