"I don't like the idea of 'paraphilia' as it treats non-vanilla sexuality as pathology"

I don't really like it either, although it can still tell us something useful. I.E. Someone is interested in certain things prior to consuming such content (and there is data to show it).

I don't think *that part* is in and of itself problematic, it is only so when someone is paranoid about that (in a manner that is discriminative against someone's kinks). *That* can be helpful in arguing against censorship or other fundamental rights violations.
