Hmm, I've compared Mark Citadel to my Bestiary of Autism, let's see which ones he fits, shall we?
https://kiwifarms.net/threads/the-bestiary-of-autism.38331/
Fan Autist: Of a neofeudal society in which he would be a god-king, definitely. Also wants to rewind time back to a period when this would have been what he considers ideal.
"Respect Mah Authoritah!" Autist: Most certainly. Has an asinine belief his enemies should roll over and die on command and his will should be obeyed despite no power whatsoever to back it up.
Raging Autist: Well, more like impotent bawling, but yeah, he does a LOT of this.
Conspiracy Theorist Autist: Makes up elaborate pretenses for why reality is not as he deems it ideal.
Political Autist: Without question, though it's more like an incredibly self serving version of right-wing politics mixed with a lot of delusions of being a god-emperor.
The Troon: Hard to say without more evidence, but his excessive, overbearing insistence on denying and vitriolizing transgender people could indicate some repressed self-hatred of desires for this very sub-type.
Laser-Guided Autist: In regards to his own ego and defense of it, no doubt whatsoever.
Sex Crazed Autist: Certainly seems to have a worrying amount of bizarre justification for the legalization of underage sex and cannot seem to fathom how fucked up that seems when rational people explain it.
Troll-Shielding Autist: DEFINITELY. Has spent most of this thread being the living embodiment of all the traits of this autist.
Imitationist Autist: Comes off like a poor man's MRA/alt-right ripoff, and it's obvious his theory of mind in regards to how he'll make it all work amounts to "because I said so".
