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.

NDs want others to perceive the most accurate picture of them.

NTs want others to perceive the best possible picture of them. That makes talking about ones strengths loaded with things like suspiction etc.

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.

You’re arguing that feeling like everyone (or neurotypical people) is mentally disabled is not an example of superiority complex, right?

1. I was being a little facetious. 2. It is absolutely weird to speak for all neurodiverse people in such sweeping ways. I've been involved in the physical sciences most of my adult life and I can tell you I've met plenty of ND people who are also highly competitive and judgemental. Even those these are considered negative traits, you do a disservice to a a huge variety of people by claiming that they are all the same. Its the opposite of acknowledging their diversity.
