I find your post very interesting, because I tend to respond almost exactly the same way when someone asks me why I'm an atheist. The one difference is the "extremely disquieting" part; I find it hard to relate to that. From my point of view, reality is what it is; i.e., it's emotionally neutral.

Anyway, I find it really curious that we can disagree so completely while employing seemingly identical lines of reasoning. I'm itching to ask you some questions about your position, but I don't want to derail the thread, or to give the impression of getting all up in your business, as it were...
