An interesting take on one of those Biblical stories that fundies always seem to bring up to justify their homophibia:
A quick summary: two angels come to Sodom and Gomorrah, and Abraham's nephew Lot invites them into his home. An angry mob surrounds the door and demands, "Where are the men who came to you tonight? Bring them out to us, so that we may know them." Lot protests, offering them his virgin daughters instead. (Yes, you read that right.) But the mob keeps pressing for the visiting angels, who suddenly strike them blind. The angels then lead Lot and his family to safety, and the Lord rains fire and brimstone on the cities.
Most scholars take the mob's demand to "know" the visitors in a sexual (i.e. "biblical") sense. Assuming they're right, this oft-cited story is about an attempted gang rape. I'm going to go out on a limb here and say that gang rape is BAD. But what does that have to do with homosexuality?
At this point fundamentalists will point to the fact that the mob declined Lot's offer of his daughters, instead demanding the (male) visitors. "Aha," they say. This proves that the story is about homosexuality!"
I always find this response surprising, since Lot's offer of his daughters is an embarrassing detail of the text - for fundamentalists. Lot is supposed to be the hero of the story, renowned for his virtue. When faced with a mob of angry rapists, what does he do? Why, he does what any upstanding man would do. He offers them his virgin daughters. If you ever want an example of the bible portraying women as expendable property, you need look no further than the Sodom and Gomorrah story.
