I'll be honest, I don't think I would've interpreted "demanding an AuDHD diagnosis" as "explaining the compounding of their issues in the language of western medicine". Especially if their issues are just oppression. Perhaps I'm just misunderstanding.

Western medicine is well aware of the fact that they can't treat the underlying cause of things like autism and ADHD. If you're a real patient with one of these diagnoses (or even depression), they will tell you that upfront. They're not pretending to fix anything with pills.
