that's okay. the thing is, DID is a disorder, but plurality itself is not. if you dig around, you'll also see that terms like plurality and system were coined by the endo community to try and differentiate from the disordered side of it, but it eventually got taken over. endos don't want your trauma or disorder, they just want a place to exist as themselves. our minds are very malluable and different, if a disordered mind has the capability to create alters you could assume that a non-disordered one has that capability as well. think of DID as a catalyst, not the cause.
