A lot to unpack here, but I'll try.
I actually agreed very much with your first sentence. Musk is certainly playing a role, to be divisive, yes. To think he cares about Autistic people? He claims to be autistic, so... yeah... It seems pretty clear Musk cares about himself more than anything or anyone in the universe.
I am not speaking for the entire Autistic community (by the way, I'm Autistic). What I said was most people in the Autistic community do not identify with Musk's bigoted, hateful views.
Of course I've never been to 4chan, and assuming that one dark corner of the web is representative of the Autistic community is incredibly ignorant... just letting you know.
Do not tell me what words I can or cannot use. Musk is a literal nazi. In addition to doing a heil hitler nazi salute (amongst many other hateful behaviours), he virtually attended an AfD rally and told Germans to "get over" the Holocaust.
