This from Amanda Marcotte, in AlterNet:
Atheist 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.
