My conclusion is that contrary to popular belief, atheism is not primarily an intellectual revolt, it is a moral revolt. Atheists don't find God invisible so much as objectionable. They aren't adjusting their desires to the truth, but rather the truth to fit their desires. [...] This is the perennial appeal of atheism: it gets rid of the stern fellow with the long beard and liberates us for the pleasures of sin and depravity. The atheist seeks to get rid of moral judgment by getting rid of the judge.
