Two things:
1. The term atheist has been vilified and perverted to mean "someone who has a fanatical devotion to the un-belief in God." Now, non-religious people of all types are scrambling to come up with new terms that they deem more acceptable, either to themselves or to others. I don't really like that. It just seems like a cop-out. We need to make people understand that atheists aren't all crazies who hate religion the way RESmonkey does. I'm not "agnostic" because I am confident in my beliefs (not fanatically devoted to them, but confident). I'm not "spiritual but not religious" because I don't believe in spirits any more than I believe in angels, demons, God, etc. I'm not a "secular humanist" because I don't identify with the term "humanist," even though I basically agree with secular humanists have to say. Perhaps "non-religious" fits me better than "atheist," but I sort of feel like I want to take the term back. Sort of how like other oppressed groups throughout history have tried to use formerly derogatory terms for themselves ("awesome dude" vs. African-American, "queer"/"i love you" vs. homosexual).
2. I effing despise anyone who tries to push their beliefs on others. In fact, I think I dislike extreme atheists more than extreme Christians. They're both bad, but since I consider myself an atheist, I don't like that those people give me a bad name. From what I understand, many mainstream Christians feel the same way about evangelicals.
