I mean, the whole (clearly political) concept of 'neurodivergence' seems ridiculously under-defined.
Who gets to be included in the "social model of disability"? Who gets to demand society accommodates their "difference" vs who is expected to adapt to society? Which conditions does it apply to, and who gets to decide who has those conditions? It's an extremely complex political/scientific question, yet that complexity is never acknowledged in the glib discussions of it I see in the media.
My suspicion is that it just ends up coming down to whether your particular condition happens to be shared by a lot of affluent white people and so has a powerful lobby behind it. E.g. autism - which has, on its team, the likes of Elon Musk, and any number of influential political and media figures who have children with that condition, so clearly autism has a lot of political clout.
Conversely, conditions that affect less powerful demographics, or which are just much, much rarer, don't have the same political power and get treated very differently.
Another question is whether it includes conditions that are dangerous to those with them? e.g. depression and anorexia and dementia? Or to others? e.g. psychopathy? Can the 'social model of disability' ever be applied to those?
Does it only include conditions someone is born with, or does it include conditions acquired from experiences? I see many promoters of 'neurodiversity' try to make that distinction, and hence exclude personality disorders, for example, effectively limiting it to autism and ADHD (with a perfunctory mention of Tourettes and dyslexia), but I don't get the logic behind that _at all_ given that formative childhood experiences are no more under someone's control than are genetics or embryonic development.
Then there are conditions that are so rare and poorly-understood that it seems nobody is entirely sure which symptoms are caused by it vs which are just your 'normal' psychology (which is pretty-much my situation). How do those fit in to the 'neurodivergence' model?
