Slavery in the bible was not the same as slavery today. It was more indentured servitude, as Jews were obligated to turn their slaves free every 7 years, and slaves were allowed to have property, had to be paid wages, and had rights just as everybody else did.
OMG...You really need to pick up a history book every once in a while.
And actually READ the bible. It ain't peaches and cream in there, Princess. It advocates slavery, plain and simple (among other things). Stoning of women and children is popular.
Oh, and my favorite story, Sodom and Gomorrah. There's a story to tell the kiddies before bedtime.
Angels come to warn the one guy in town that god has decided is worth saving. The town, you see, has gotten away from the Christian ideal of "love they neighbor" and were very inhospitable to strangers...kind of a gated community you might say.
But when you enter a town and are not welcomed, go into its streets and say, 'Even the dust of your town that sticks to our feet we wipe off against you. Yet be sure of this: The kingdom of God is near.' I tell you, it will be more bearable on that day for Sodom than for that town. (Luke 10:10-12)
So anyway, back to the story...The townspeople find out about the angels staying with this dude Lott and his family and they get a mob together and head over to Lott's house. You get the idea from the story that these townspeople want to gang rape the angels (not have consensual loving sex, but RAPE them). So this guy Lott, this loving Christian, family man, offers to send his two daughters out to gang rape them instead of the Angels. Real nice guy, that Lott. Father of the year.
God destroys Sodom anyway, including Lott's too curious wife so he runs off to the hills where he has sex with his two daughters.
And out of this whole story, who gets scapegoated? Consenting adult gays and lesbians, who had NOTHING to do with the whole story in the first place.
