I frequently hear the claim that atheists choose atheism, usually for some morally blameworthy reason like a desire to avoid taking responsibility for their sins. My response is basically the same every time: You may not believe me, but I didn't choose any such thing, and I can't just 'choose' to start believing. Maybe you can, but I can't. I do not believe in any gods. Evidence would make me believe in some god, but all the playacting in the world isn't going to change that.
