Autistic people are often seen as arrogant because they speak honestly about their strengths (and weaknesses), whereas normal people avoid speaking honestly about their strengths unless they are arrogant.
This is many times in my experience not the case, autistic people still have very strong biases hidden under a layer of seeming logic. Incorrect, very confidently held opinions (perseverance -- the trait) are things I see often in the community, I believe.
Bluntness != correctness.
We have the normal emotions and human flaws, they're just expressed differently.
We are also liable to mistake politeness and tact for incompetence or foolish "herd behavior." Something I've realized as I've aged as an autistic person is that I was quite obnoxious about this in my youth. Neurotypical people are typically much more aware of the social context of their words and actions than we give them credit for: they aren't stupid they are trying not to embarrass us or be cruel.
