Dumb question: Are most of the family members Autistic?

Dumb thing i've been thinking about for a while; do you think autism runs in the sawyer/slaughter family? There's quite a few signs of it and it's an interesting, slightly different take on these cannibals that i haven't seen before. It also just seems somewhat likely, as autism does pass down through genetics, and they sure show a few of the signs, such as;

Hyperfixations (cannibalism, leather/slaughtering, flowers for sissy/nancy, masks for leatherface, pictures and traps for hitch etc)
sensory overloads (cook's hearing ability, the family's general sensitivity to audio cues, nancy's animation after using her eye ability, the small tantrums after grapples and stuns etc)
tics (sissy's singing, Hand's weird grunts, the characters fidgety idle animations where they're usually seen fiddling with their weapons)
repetitive behaviours (The family gets in a cycle of killing people and then stressing out to clean up the victims. The game takes place 6 months before the movie, and it's basically the exact same thing happening twice)
plus the fact both hands and bubba are non verbal...

As someone on the spectrum, it was just interesting noticing these awful, horrific people displaying these familiar traits, and now i'm just curious if anyone else has anything to add/debunk this crackpot theory?
