I know I'm going to regret poking the Hilgya discourse, but isn't saying arranged marriage is bad because it's sex trafficking kind of like saying assault is bad because it's murder? When you want to talk about how awful something is, exclusively referring to it in reference to some other worse thing obscures your point. That's not the only reason that argument is messed up but it's the most perplexing.

Anyway Hilgya is unapologetically apathetic to the feelings and safety of others and no amount of backstory is even attempting to justify that so the whole train of thought is a red herring.
