First, as a parent of a child with autism, I do not consider it an insult to question whether someone has it, but doing it in such a public way is classless. Typical of the source.
Secondly, from the limited amount I have seen of Baron, I do not pick up on anything that would make me think he was autistic. Specifically, on election night, he looked like a tired kid who just wanted to go back to bed. It was freaking 3 a.m. when the Trump family walked on that stage.
