Just bieng socially ackward does not make one autistic, far from it. But autism is heavily hereditary that would increase the odds of him bieng autistic. Having an autistic family member increases the odds that a person may have several strong autistic traits but not enough of them to be autistic.

“My autism is not a superpower. It also isn’t some kind of god-forsaken, endless fountain of suffering inflicted on my family. It’s just part of who I am as a person”. - Sara Luterman
