One almost sure way by which revealing you are on the autism spectrum end up resulting in an undesirable societal outcome: when sharing your own perspective on some social issue, some people now can simply disregard your opinion based solely on it being "most probably too dramatic" [there's irony here in so many levels!] to be taken seriously. (This coming from the same people who keep accusing you of being "too objective" when dealing with concrete issues [!]; also same people who have accepted approx. the same perspective from you on the same issues until mere days before knowing you're autistic).
In this context, it's possible that the revelation serves an important kind of purpose here, by offering yet another "reasonable" justification for people to opportunistically handwave out difficulties related to some relevant issues (difficulties pointed out by people who suddenly loose a significant part of their credibility).
Yeah, there's some actual personal experience behind all this whining. But I'm not saying this out of spite (in principle, it would hardly be a surprise to know that I seem to suffer from a disorder that renders me somewhat less able to feel offense than the average person - even when I can clearly identify the intent); what really bothers me here is the sheer irrationality of the whole behavioral complex (from a collective perspective).
