It will never be said that you allowed your lack of knowledge to hold you back.
You Funditards and Wingnuts usually spend a lot of time pointing out how certain misogynistic cultures just show how backwards the middle east is...
...and yet you are defending offering two women up for gang rape.
Incidentally, there is a paralel for the Genesis 19 story in Judges 19. Once again, a mob from the Tribe of Benjamin demands that a Levite be handed over to them, and the offer the man's concubine instead. the woman was raped to death, and the Levite cut her body into 12 peices and sent them off to the other tribes of Israel, demanding genocide of the Tribe of Benjamin. All but 600 of them were killed.
So, yeah, that's pretty fucked up. So where is God when this was going on?
