I've mentioned previously that a lot of the recent mass shooters seem to have had Aspergers, or possibly a stronger form of autism. Another thing I've observed about Aspies is that they feel freer to hit people. This is obviously a far milder form of aggression, but it's hard not to notice the correlation.
I'm not sure exactly why they do it. It could be a reflection of their tendency to lash out when they feel they've been spited. It could be an inability to deal with frustration. It could be partly just a simple lack of empathy.
But they do lash out, and always seem to feel justified. I was once punched in the shoulder by a female Aspie, four times in a row. It didn't hurt, and when I laughed, she got even more infuriated.
I've was once kicked in the leg by another female Aspie; that did hurt. And when I expressed annoyance and told her how much it hurt, she laughed, thinking I was lying.
In a way, Aspies are sort of a modified version of a full blown autistic who'll go crazy and start hitting you. (Think of the title character's mentally disabled brother in There's Something About Mary, who seems to have been created from firsthand experience.)
When I was a small boy my parents were friends with a couple who had a daughter about my age whom I've always thought of as retarded, though she had no physical manifestations as with Downs Syndrome. When the families got together to go camping, she would occasionally get excited and just start hitting me for no reason. I would just look at my parents, or her parents, and her parents would always gently remonstrate with her and pull her off me. In retrospect, I wonder if she didn't just have full blown autism.
I'm reminded of her when I think of how I've been hit by people with the far less severe form of autism, Aspergers.
If anybody has had any similar experiences, I'd be curious to hear about it.
