@Superfreq Plurality is a superset.

For example, our own system isn't DID type, it's schizo-type.

All DID is plural, but not all plurality is DID.

Also the neurodiversity community as a whole has been trying to remove both the stigma and tragedy narrative from these sorts of disability. A lot of people clutch their pearls that if you don't hate being plural that it "doesn't count" and take great offense to that as though by enjoying your existence you are somehow intruding.

This is the same as the LGBT+ community was before Stonewall, and history shows we(p) are MUCH happier after that (we(s) are also bisexual and trans).
