As an aspie the whole notion of autistic screeching is kinda funny. I'm not saying autists cannot be pre-occupied with stuff and very "enthuisiastic" about special interest but it feels like most of the time the people doing the "austistic" screeching are just neurotypicals who desperately want to belong in a group (group conformance drive tends to be a bit lower among autists).

Meanwhile plenty of "social justice" types have no trouble attaching negative stigma to autism because apparently that's not a protected disorder.
