I voted yes, because my understanding is that if I say "yes" you'll try to shoot me but the gun will jam and you'll still shoot everyone in the cafeteria. Something like that.
But seriously.
I'm a "yes," by choice. I do choose to believe, and I am aware it is absolutely possible to live in a world without that belief, if one chooses to. Neither do I think that belief is punished or rewarded.
As to my reasons, they are subjective, so it's rather insulting to attempt to foist them on others.
I cannot objectively prove a subjective phenomenon; but since the reverse is ultimately also true, if I'm feeling particularly solipsistic, I'll just wonder why the hell I allow figments like yourselves to annoy me so much, or why I would have created the annoyance of work, for that matter.
