Just to explain the cultural context in which
@azaz used it: in /r/wallstreetbets (WSB) subreddit speak "autist" is used in a self-referential description, never in an aggressive-negative context or as an insult.
"Us autists" who are "on the spectrum" are meant as a socially awkward but elite group of outcasts, with a bit of a self-deprecating but endearing overtone. "Be a true autist" is meant as someone having all the best traits of this subculture, where "Papa Musk" is considered a hero autist.
Just to get a feeling of it, watch this WSB investment advice video from two days ago (erm, strong language warning):
(There's even a TSLA reference in it.)
Or these self-identifying references:
I.e. this WSB use of "autist" is
very different from the alt-right and 4chan use where it's indeed meant as a nasty insult.
/r/wallstreetbets basically turned around the alt-right semi-racial epithet of social exclusion and inverted it into a desirable, inclusive trait.
They even inverted the word "degenerate" in a similar fashion: via a CSS hack of the WSB moderators the number of subreddit subscribers on WSB is displayed not as "893,929 subscribers", but as "893,929 degenerates".
By subscribing to WSB you/we self-identify as autists.
