Didn't I just sorta deal with this yesterday? What part of "atheists are atheists because we don't have faith" don't you understand?
I doubted the existence of god long before I could be called "angry". And any anger I do have is not directed at a non-existent entity... it's directed at his idiotic followers for continuing to insist that obviously false things are still somehow true merely because they wish it to be.
But worse than that...
Does a question constitute a proof? Why does an atheist's anger have anything at all to do with the truth or false value to the claim that "There is a god." If you met an atheist who was happy-go-lucky, would that prove there was no god?
