I think jar meant to refer to
Genesis 19, the story of Lot and the city of Sodom. That's the story fundies often use to condemn gays, in spite of the fact that the hero, Lot, attempts to pimp out his virgin daughters and later gets drunk and impregnates those daughters. Since the apostle Paul refers to this would-be pimp as a "rightous" man, I don't see how anyone can possibly consider the bible to be an acceptable moral guide.
In any case, I agree with jar that the story you cite is simply an alternate version of the Lot story. If there is a point to it I can't discern it. Such stories are simply the musings of pre-historic tribal nomads.
