Pics or it didn't happen. Also, prove Jesus didn't do the same thing.
If we're judging the past, I'd file the Quran into evidence as a written confession. He was a 7th century warlord, he conquered and killed. He held slaves. He played by "old enough to bleed, old enough to breed" rules. And it's not like this was some kind of secret or radical exception to his contemporaries, same as the Founding Fathers kept slaves. It's the past, it was ugly but it's also history. It's only a problem when somebody says the 18th century was perfect, let's go back to the way things were in 1776 and freeze society the way it was. Or well, the Amish pretty much do that and it's not a big problem, it's the "or I'll chop your head off if you don't" fundamentalists.
