The recent edition of the Pew Forum has apparently revealed that 21% of atheists believe in god (I did not find that in the poll, but found it cited on a different blog). Susan Jacoby has written an essay about it. I have to say that I agree with her: an atheist that believes in god is not an atheist. He or she is just confused about the term.
So I want to be clear and make sure there is nothing ambiguous about my stance. I do not believe in god. Therefore, I am an atheist. I did not 'become' an atheist because it was cool or this year's must-have philosophical accessory, but because, after careful research and thought, I have concluded that the chances of god existing are extremely slim.
There you go.
