I have talked with people, rarely are the people pushing for “Person with Autism” the same ones saying it is a disease needing cure or treatment. They tend to be the individuals who are most likely to be interacting or advocating for autistic people, however they learned “Autistic person” the person started to be ignored, they decided the best way to solve that issue was to put person first, and to their credit, it can work, however it just shuffles the issue and postpones the same issue this linguistic trick was started to avoid. It was after the retorical change that groups like Autism Speaks decided to run around saying this proves its a disease that needs cured. No one changed their mind over the reshuffle, it was just that it is clunkier than the previous it knockes some people out of automatic thinking
