You are absolutely right to be offended. I have neurodivergent people in my family. I love them dearly. I wouldn't want them to be any different. My father (likely) had autism. He was a professor who got invited to lecture at the Sorbonne and wrote something like 30 books. My brother has autism. He makes far more money than I do because he's a really good coder and he's happily married. Neurodivergent people can live lives as full of success and happiness (and lack of success and unhappiness) as anyone else. They just do it differently.

Acting like autism is some sort of horror that parents should fear is disgusting.
