I'm not sure what you mean by "dysfunctional autism" exactly, but this is a known trait of many autistic people. They often fail to pick up on social cues that most other people take for granted. It's just because their brain works differently, they tend to take people at face value. And unlike what some have professed to believe here, their desire to explain or correct you does not come from a desire to "be the smartest person in the room", but rather it's their way of helping. They like to have accurate information, so they assume others do too. So yes, combine these two traits with a person who like to screw with them and you get conversations like this, which unfortunately amounts to a pretty nasty form of teasing.

Because apparently for dudes who've got a compulsive need to be the smartest person in the room, "someone who's wrong in a really stupid way who has unshakable confidence that they're smarter than you" is their kryptonite. You can play dumb on almost any subject and their ego, their staunch belief that the masses are so far below them, will blind them to the fact that you're just fucking with them, and as long as you don't admit you're fucking with them or acknowledge that there's anything Off about what you're saying, they won't be able to stop themselves trying to get you to Respect Their Authority, and they won't be able to see that will literally never happen.
