It's just that the man when buying sex is not (as much) sinning, but the woman who allows him to buy sex is very much sinning.

Absolutely. Like medieval Christians couldn't lend money to each other with interest, so they just found a Jewish person, and used them as an intermediary as they could lend/owe with interest to non Christians just fine lol

And my medieval example is completely topical cause these religions have hardly advanced since then.

There's a lot of this in Abrahamic scripture. The nice treatment of slaves, for instance, only applies to fellow Israelites who sell themselves into servitude. Non-Israelites can be bought, sold, kept forever, bred (and their kids are slaves too), and even killed with impunity.

Biblical scholar Dan McClellan notes that people from every age have to negotiate with sacred texts to affirm the ethos of their time and explain away those parts that don't work anymore. And this is true with all religions whether Jewish, Hellenic, Wotanic, Shinto or whatever.

So yes, in Islam, sex work is haram until it isn't.

That's literally in their book, it's not even rape. let alone wrong at all, if the victim isn't Muslim, with a small exception for married women regardless of faith.

Well if course. The other tribes are humans but not people. This is pretty freaken universal for conservatives everywhere.
