Having watched the video (I'm still wading through the document), I honestly don't see any ASD-type behaviors. What with giving birth to two, and marrying one, I'm pretty familiar with various forms of high-functioning autism, and I just don't see it. What I see is narcissism, sociopathy, entitlement, possibly some borderline personality traits. A deeply indulged, spoiled brat who comes across as extremely creepy.
He poses for the camera, he laughs his rehearsed laugh, puts his chin on his fist just *so* as if he's practiced it thousands of times for the camera. He films in his car, to show off his BMW.
In the document, he complains that it's everyone elses' fault that he's unhappy. He blames his short stature. He blames his parents for not buying him sufficiently fashionable clothes. And he cheerfully talks about throwing a huge tantrum when he didn't get the bedroom he wanted in his father's new house, when he was in 4th grade.
It just doesn't sound like ASD to me, after 29 years of raising two of them, and being friends with many more.
