"Autism," as an insult, is going the same way that, "retard," and, "faggot," went. It's being overused to the point that it's lost all meaning, is borderline offensive (but isn't because people don't mean it the way offended idiots interpret it), and is pretty much as impactful as the word, "fuck."
"Weaponized Autism," is really the only funny meme to crop up from this new wave of replacing the word, "stupid," or, "idiot," with something else. Eventually it'll become normalized and you'll see something else being used. Give it a few years. Or just hope that some z-list internet celebrity with a mental illness that isn't autism does something really noteworthy so that people start associating their illness with stupidity and we start hearing a different word, I guess.
Speaking of retarded, though, I'm pretty sure it's common knowledge that tictac lives in a shitlib fallout zone. Can't remember very clearly if it's Commiefornia or Arizona but I do distinctly remember him saying he'd be fine with nuking Commiefornia even though he lives there.
