Do Atheists Choose Atheism?

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.

Why? Because belief itself simply does not appear to be a matter of will or choice. A real problem with this idea of "voluntarism" in beliefs is that an examination of the nature of holding beliefs does not lead to the conclusion that they are very much like actions, which are voluntary.
