I think I am in a similar position to squizita, in that I have some mild traits (my partner has much stronger traits - can't make eye contact when he is tired or stressed, has to be prompted for a lot of 'normal' behaviour etc).
It would be entirely futile for someone to explain to me why something is 'wrong'. I will give you the example of what some would call 'pedantry'. There are some things that I come across as very pedantic about. I am usually very meticulous about language use, and my natural assumption is that everyone else is too. Why wouldn't you be? When someone else makes a mistake, I often try to help by telling them what it should be. This upsets a lot of people. I have gleaned that it is because people who correct others are 'smug'. Now, I am anything but smug. I am trying to be helpful, and I certainly do not think I am better than somebody else just because they didn't know something or made a mistake. Nobody knows everything and everybody makes mistakes.
So, I know that some people get upset when they have their error pointed out. Some people think I am trying to make them feel bad. Some people think I am smug. Fine.
I still explain the correct use of language to people. You could repeat the above to me until the heat death of the universe, and it would not make any difference. I still want to help. I suffer from anxiety. I have a horror of upsetting people. I still want to help.
And I don't have any diagnosible autistic disorder. I can't imagine what this would be like for someone who does.
I think that, to a certain extent, expecting someone who does have AS to behave as if they were neurotypical is like asking a wheelchair user to go for a walk. For some, it might be possible for a while, but it might not be advisable.
