Morality without God

Man, I hate the accusation that just because I don’t believe in a sky-deity I suddenly don’t possess any morals whatsoever. Who decided the only way to “be good” was by blindly accepting the moral edicts of a 6000 year old manuscript? Did everyone suddenly forget the fact things were pretty fucked up back then? What parts of the Bible are still moral by today’s standards? How about selling your daughter into slavery, or murdering your family members if they didn’t believe in the same God as you? Talk about a great moral tome!
