My parents used to be the kind of people who thought autism == rain man, which is funny because my dad often displays some very aggressively autistic behavior (you know, things like inflexible routines, food and texture aversions, gross misunderstandings of social cues which have led him to quite a few actual fights, draconian rule following and imposing, an obsession with guns, yadda yadda) which he thinks is perfectly normal and "how things should be", because "that's how he was raised and is therefore good", according to him.

And, obviously, when some of those behaviors crossed over to me, he thought it was perfectly normal as well lmao

(I say used to because I've been trying to educate them a bit but man is progress slow)
