Not the person you replied to, but this is a nuanced conversation, much beyond the simplicity of disabled or not.
Deafness is the one that comes to mind,
there are others that do as well, but I grew up in a Deaf household so I know a bit more about it.
For a group of Deaf people, they quite like being Deaf, they have their own language and schools etc. Those schools arent particularly decent, but for the group that like being Deaf they dont care. They'd rather fix the schools then fix their kids.
The notion that disability is a social issue is true, but fixing society to cater towards most disabled groups is a far greater task in most cases. Obviously Deafness and others are the expection where it is felt that it is easier/better to fix society.
Deafness has been "curable" for a while, yet i was raised to see that cure as a form of genocide, trying to erradicate a linguistic minority, rather than fix them. As without deaf children, it was very unlikely anyone would pick up their language.
I frankly think that there is no downside to try to be positive about disablilty, i say this from the uk, where the rhetoric has been destructive beyond belief. That said it is all very case dependent.
