Tbh, I don't think it's that surprising. I've read people describe AGP as, at root, a humiliation kink; and men have thought women were disgusting and inferior for thousands of years. The Roman emperors Nero and Caligula were said to cross-dress at times.

Yes, I guess you are right. The ultimate root is male oppression of females.

The connecting thread that links AGPs over time is that they hate and abuse women.

But it's more than AGPs, isn't it? If men, generally, did not oppress women, generally, then there would not be a sex-linked humiliation kink in the first place . . .
