Etymology of "aut-ist"
From etymonline.com/word/auto- and /-ist
>auto's root is: self, one's own, by oneself, of oneself
>ist's root is: one who does or makes
So an autist is one who does or makes oneself or on one's own.
If doing oneself, he's calling us a bunch of jerkoffs.
If making oneself, he's saying we are self made or possibly independent. I would guess that means "folks not connected to others," which might mean not part of the cabal.
If he just made up the word, he's combining some word that begins with aut(o) and "makes or does oneself."
Anyone have any insight where to go next?
