I think autism, or any psychological condition for that matter, is just such a conveniently simple explanation that few people can resist it. Perhaps such people feel there's no need to question these incidents any further to find out the explanation for this type of behaviour. You can simply say that someone is not an NT therefore they must be psychotic and out of touch with reality. Case closed.
Boy, humans love to boast about their complex brain structure, but too often they don't bother to use the extra space in their left frontal lobes to analyse a subject in full.
There was an incident at my school last year that was very quick to spread around the gossip grape vine in which a 16-year-old boy "randomly" attacked an older student very aggressively. In view of the trauma that the onlookers might have experienced, a whole school assembly was arranged to "explain" the incident. We were basically told that the boy was sent away and not to worry because we'd never have to have anything to do with him again. I don't even know if he was autistic, apparently they thought it was enough to know that he wasn't an NT. One of the co-ordinators at least understood that the noisy environment of the study centre might have triggered that response, but, as Soup and SpinningCompass have pointed out, a comparison with how this incident would have been dealt with if it was an NT is very revealing.
If it was an NT, people would certainly want to know the full story of what caused the event, what caused him to lash out, what did the other person do to him, what had happened prior etc. As it was a first time, he would have been suspended, or expelled, but not "sent away" to where such foul, hellish creatures belong.
Anyway, inmyworld20, I always believe that an Aspie should inform everyone that needs to know about their Syndrome. Explain it as best as you can to them though, talking about how it affects you personally, and if you have time you could have a discussion about diagnosis and the history of the Syndrome and all that, but make sure they understand you.
You can't really hide Asperger's. People will always eventually discover you have it, even if they can't put a name to it, and can't understand it. I think you might as well explain it to them. It's the only way to combat these generalisations, and they really are no excuse. Withholding that information because you're afraid they'll assume that you're violent is like being afraid to tell people that you're a Muslim because you expect them to think you're a terrorist. In my view, both cases are equally ridiculous and unjust.
