What objectively good, moral things did the Quakers do that could NOT have been done by an atheist? Name ANYTHING that is objectively moral that a theist can say or do that an atheist cannot. Hitchens posed this challenge and offered $10,000 to anybody who could do this. Nobody could. In the end, it just doesn't seem to be possible. You just CAN'T prove that religion makes people good. Similarly, as anti-theist as I am, I concede that it doesn't TURN people bad. People are good or bad alongside being religious or not. Religious beliefs don't actually MAKE you a good person--or a bad one. Scripture is a wonderful tool and is so arcane and ambiguous that you can find support for nearly any argument if you choose to interpret or exploit it that way.
Religion can certainly be used to persuade or manipulate people to adopting certain beliefs or ideals, but so can other philosophies in the right hands. It's not a power religion itself has, but rather the way it's being used and the people it's being used ON.
Even if it takes all day, at this point I just want to know what you think religion has caused people to say and do that's not only objectively good, but also something unique to religion.
