Atheists are routinely asked how people will know not to rape and murder without religion telling them not to do it, especially a religion that backs up the orders with threats of hell. Believers, listen to me carefully when I say this: when you use this argument, you terrify atheists. We hear you saying that the only thing standing between you and Ted Bundy is a flimsy belief in a supernatural being made up by pre-literate people trying to figure out where the rain came from. This is not very reassuring if you’re trying to argue from a position of moral superiority.
