You're familiar with the satirical wit of "The Onion", right? Well, they have a new "Book of Known Knowledge". I got it from my library. Here's their definition of atheism.
Atheism, rejection of a belief in the existence of God in which one deeply devotes oneself to the nearly nonstop studying, writing, thinking, and talking about God. Upon raching the philosophical and logical conclusion that God cannot exist, an atheist will dedicate the rest of his or her life to poring over books about God, fervently arguing with those who believe in God, and meeting with other devout atheists to discuss God or listen to someone lecture passionately and at length about how there is no God. The firmly held belief that there is no God gives atheists a deep sense of purpose and meaning in their lives.
I don't know about you, but I love it! That's exactly why, in my very first Nexus post, I said I probably wouldn't write much about the subject (nor read other posts about it), despite this being a blog site explicitly for atheists. 'Nuf said.
