The people I've known who have Aspergers Syndrome would frequently castigate others for their behavior. They were forever telling others that they were acting inappropriately, as if they themselves had any sense of what was appropriate or not.
With Aspies, it's as if they think the sheer vehemence of their disapproval will somehow demonstrate how sane and socially clued in they are. The equation goes something like this: the more offended they act, the more they think they are proving how refined their sensibilities must be.
It's pathetic, but that seems to be how they think.
It's not dissimilar to liberals who claim to be offended all the time. They seem to think that by saying, "I find that really offensive," they are demonstrating moral superiority.
Sometimes I feel like responding, to both sets of people, "Ah, what an exquisitely sensitive and enlightened person you must be -- especially compared to a moral reprobate like me!"
