r/Fitness does a weekly "Moronic Monday", a judgment-free thread where people can ask questions that they would ordinarily feel embarrassed for not knowing the answer to. I thought this seemed like a useful thing to have here - after all, the concepts discussed on LessWrong are probably at least a little harder to grasp than those of weightlifting. Plus, I have a few stupid questions of my own, so it doesn't seem unreasonable that other people might as well.
I can't speak for the other ones, but Buddhists at least don't have a "hell" that non-believers go to when they die because Buddhists already believe that life is an eternal cycle of infinite suffering, that can only be escaped by following the tenants of their religion. Thus, rather then going to hell, non-believers just get reincarnated back into our current world, which Buddhism sees as being like unto hell.
