I've come across a couple of things about this in the last few years that have stuck in my mind but I cannot provide links I'm afraid. One was a podcast in which an ex Muslim woman was saying that the reason the Pakistan men are so organised about this is because they also do it in Pakistan, essentially they are well practiced at it and just do what they do there. It might have been Jasmine Mohammed but I am not sure.
The other one was an article in a publication, maybe Unherd or The Critic, written by a young Pakistani man detailing the sexual abuse he was subjected to by his uncle when he was a child, in Pakistan. There was nowhere for him to turn, the women in the family would turn a blind eye but they have no power or influence anyway, and would probably get beaten if they tried. He thought if he took it he would be protecting his sister, but it turned out she was also sexually abused by the same uncle.
All in the context of a very clannish social system which seems to have more to do with Pakistan than Islam, and Islam tends to hoover up an incorporate a lot of what's already there. Behind closed doors, say nothing, boys are abused as well and the women and children have nowhere to go.
I guess, much like other countries, Pakistan wants to pretend it couldn't possibly happen there, but the whole point of the young man writing the article was to say yes it does, to boys as well, it's just hidden by a closed social structure where the abusers have the power. Class doesn't seem to make much difference either, he was well educated and no longer in Pakistan iirc. It's depressingly universal, and sanctimony is cheap.
Edited to add, just to be clear, I am not letting Islam off the hook for its attitudes to women, this is in relation to this particular country.
