People who can't understand social cues can often come off as abrasive or cold to other people. It often takes a fair amount of work from neurotypical people (not denying it doesn't take the same from autistic people) to fight emotional programming and not be bothered when autistic people do things neurotypical people wouldn't.

I think being both willing and able to conquer instincts and social programming is part of what makes someone less likely to be reactionary.
