A question for those who've read more of the Bible than I have:
The scenarios being pointed out, the rape, sex, incest, polygamy, whatever have you, are they written about in a way that's meant to be erotic? Or are they framed in a storytelling way as many other old stories set in a more brutal and oppressive time, dealing with similar themes, are written?
Not that being non-erotic makes it any less nonsense, it's just not sexy nonsense, and the comparison to pornography falls flat.
