I’m glad you are making the point that there are neurodivergent people from every ethnic group. I am not autistic, but my brother is and I can definitively state that because of where he lands on the spectrum, there are times when he cannot control his behavior. Now, I’ve never heard him yell at someone for being ableist, but that is a thing, both systemically and individually. Just as many white people were explicitly or unconsciously conditioned to see themselves as better than or more worthy than people of color, those who have full mental or physical capacities are explicitly or unconsciously conditioned to see themselves as more capable and more valuable to society.
