Fair distinction on the identity-only bit- I didn't think that through all the way. However, I do refer to myself as an autist, and I know plenty of autists who feel the same (I make it a habit to ask). Similarly, I refer to myself as bipolar and, naturally, as a narcissist. Hell, even "ADHDer" has become a thing, bc people like nouns. There's no noun version for bipolar yet, but I'll be using it if it ever becomes a thing.

I don't think it's dehumanizing; I think it's empowering, like taking back the word queer. It absolutely does rub me the wrong way though when someone who doesn't fit the category does it though
