Quote from Madison:
as opposed to the kind tenderness of the Old Testament? have you read that thing? -- God killing children, throwing burning sulfur on homosexuals, human sacrifice, condoning slavery, etc. stuff osama could only dream of...
now if the argument is instead that modern people should disregard or liberally interpret the bible/koran/whatever, that might be a stronger case.
What's so terrible about all this? Have you never heard about Hell? Hell seems to be much worse and it will last forever!
