Systemic ableism is the problem, not “having to deal with being neurodivergent”. Otherwise there would be no “solved” state. Though a solved state is pretty easy to get a decent definition of: A state wherein neurodivergent people have a equal outcomes in each area with respect to their neurotypical counterparts with the same base aptitude in the same subject matter, regardless of the differences in the path needed to realize whatever that aptitude is.
Now, that said, that only describes something that is lacking. I haven’t even heard of an education system that doesn’t specifically punish neurodivergent behavior, which, worse than something that is missing everywhere, is a negative that is present everywhere. So let’s call eliminating this a compromise solve.
As far as the ethnocentrism argument and it only being relevant if it’s solved somewhere, well, I guess the poor construction of that would be: “The ethnocentrism argument is only valid if there is an example of the problem being completely solved.” which I guess you sort or addressed effectively and I may have sloppily implied by accident. What I really was trying to say though, was, “The ethnocentrism argument only applies to this specific observation if you have an example of a school system to which the observation does not apply.” which I still stand by and still doubt you have such an example.
Stop saying you know if you haven’t done it. If you knew you would have done it.
