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 considers himself an atheist makes the same impression on me as someone who considers himself an afsmist. And indeed, the atheists I feel most connected with are the ones who shrug at the whole concept.
