You know Autists, ADHDers, and Audhders, have to educate neurotypicals about what our very-much-not-scary differences are. It's like most people preferring to sit on a chair, but a small number prefer to sit on a stool, or perch on the chair arm, or even to lean against the wall. See? Not scary.
I think myself, that psychologists, psychiatrists, and neurologists, are the ones who 'need' us to be categorised, studied, and 'diagnosed'. I also think that a lot of them are making a hash of it, in order to keep the grant money rolling in. #JustMyOpinion.
