Is that really a thing that happens?

While I'm sure there are rude people with Asperger's out there, rude neurotypicals can potentially be damaging in a far more efficient manner by knowing how to twist the social norms to give the pretence of staying within their boundaries.

Replace "aspie" with "black man" and your entire response is blatantly prejudiced. In my experience this is a boogieman people fear will crawl out from under their bed at night. All but one of the autistic ("aspie" is outdated) people I know understand their shortcomings and adapt as best as they can. There will always be assholes in every group; if you're not prejudiced, you judge the asshole rather than stereotyping the entire group.

Nearly all autistic people know they act weird and would like to act normal but don't know how. You have to weigh the costs and benefits. What's worse: you are occasionally made uncomfortable, or an autistic person gets fired? Are you willing to make no compromise in this conflict with coworkers? If so, it would be hypocritical.

Not remotely comparable unless you are implying that black people “expect others to change behavior to adapt to themselves, but refuse to change their own behavior” which by the way is pretty racist.
