> I agree the term is vague. But what then would you have us call it?

That right there is an admission that you're just using the term as a generic "person bad" term, which is bad in itself. It's evil to intentionally conflate and manipulate language to serve political goals. You would object to taking a person that's known to be a Nazi and calling them autistic, or vice-versa. That you are not objecting here is malicious.
