I think the mistake you're making is in equating it with choice.
One of the things that autism does is kind of limits your range of responses in a sense. You can get stuck in ruts too.
Think of it as - sometimes your brain just sends you the wrong emotional signals about what's going on. And you literally have no way of knowing innately that they're the wrong signals.
Now - imagine how hard that would be to live with and navigate through even without people going out of their way to pick at you, accuse you of being able to do something you can't always do.
Kind of like - if you were to walk up to a sheer wall of ice that was 20 feet high, and were supposed to climb it without any equipment or anything, just - climb it in 60 seconds. No help. No tools or anything - go.
Is it reasonable to expect you to take flac for not being able to do it? Would it be reasonable for people to pick at you for not being able to do something you simply aren't equipped to do?
Just speaking as a moderator - I'm not going to go around banning people just for not understanding how an autistic person's mind works.
But - as a person I think it makes us stronger if we at least try to understand where people are coming from.
The other part of it is - given the combination of the perceptive and social hurdles, and the fact that people can be mean - I mean even without being paranoid, people can be really put off by something like autism, especially if they don't know what it is or that a person even has it, I'm amazed every day by what he's able to accomplish socially.
That he can get out of bed and jump into the world in any way at all, is something that I have to tell you I'm often awestruck by.
I have all the same communication problems with him that everybody else does, but I tell you he just amazes me.
