Friendly Atheist and Friendly Humanist have both written about today's Atheist Pride Day, and--although I'm not a Facebook user--I think it's a great idea. (If you're on Facebook, check out the APD event page and do your part in increase atheist visibility!) FH has some good words that I'm going to borrow:
I am an atheist - I do not have a belief in a god. This position, as part of a wider humanist outlook, guides my daily choices, both profound and casual.
I am proud of it, because it is a worldview I have come to through a great deal of questioning and thinking.
I am proud of it because this vein of human thought has a long and noble history, from Socrates through the Enlightenment to modern secular societies.
I am proud of it because my atheism, and the humanism which it is a part of, represent my best self - the best things I do, and the things I strive for but sometimes (often) fail to do, are informed, motivated, and inspired by atheism and humanism.
So, where's the parade? (If everyone could bring a blank sign, that would be great!)
