That you can confront them by holding a fucking mirror up to them, and they still somehow don't get it. You literally show them a list of everything they will ever say in their lives, and they go, "I don't get it. So what if you could program a bot to come up with everything I will ever say? Yikes! You're toxic!"
They think nothing of the fact that they all pretty much look the same, too.
And if you show them that prior to 2012, all SJWs were saying things that would get them "canceled" today, but sane anti-SJWs had the exact same views they have today, they still don't get that it's they who changed, and not some epidemic of "literal Nazis."
The level of autism these days is another thing. It has to be intentional. Look at Swain-Tran (Newbielurker). It's not possible for anyone to be this stupid. That's what "weaponized autism" looks like. "You can't insult me, because I don't understand your insults. You can't argue with me because I don't understand literary devices. I will straw man you and accuse you of straw manning me when you accurately connect dots from what I have said. I will insult you and ban you for disagreeing with me, but if you insult me in response, I will accuse you of insulting me for merely "disagreeing with you." I will pretend that obvious insults dripping in snark were not insults, because I will take them literally, because I will pretend not to grasp literary devices."
