Obviously, our two options here (and pretty much always are) "don't use this word because it hurts feelings and reinforces stereotypes" or "let's all step back and try to decide/encourage the idea that it is actually useful enough to use" Here, the latter seems appropriate? "Disorder" is "out of order," it is something that is rare. I suppose "rare condition" might work too, I'm open to suggestions.
