The word atheism is actually comprised of 2 words: 'a' and 'theism'. 'A' stands not for 'anti' but for 'away (from)' and 'thei' stands for Dei which means God.
The bottom line is that I think that by considering myself an atheist I would pay too much honour to the God concept. Someone who is proud to be an atheist makes to same impression on me as someone who is proud to be an afsmist. And indeed, the atheists I feel most connected with are the ones who shrug at the whole concept.
