if i had to speculate why aspies aren't a huge fan of the DSM recently vs other brackets
rearrangeing the deck chairs on ADHD, ADD, whatever insertion and removal of letters, doesn't actually affect the treatment and handling.
the deck chair rearranging on schizophrenia (separating DID/MPD/BPD/general schizophrenia) is narratively problematic (so much cultural baggage already involved in tying them as the same thing) but does correspond to "these were actually not related, we appropriately separated them"
the collapse of things in to "autism" doesn't quite do the same thing. it just collapsed the high functioning group in to the low functioning group and goes "they're both bad at talking to NTs, so it must be the same thing -> same treatment" and it's not, and a lot of the backstop on this relies heavily on the "asperger was a nazi" narrative. (nevermind there was another guy who wasn't a nazi, who discovered it sooner, you could have just renamed it to that guy)
communities sort of cluster by shared experience and "highly intelligent, too literal" doesn't really share a lot of experience with "non-verbal drooling on the floor,"
hopefully the practitioners do or push for re-partitioning to some degree because one group the treatment is "here's social skills training to talk to everyone else" and the other is..

so much more cooked
