With how widespread it is, labeling, self-diagnosing, inquiring about yourself, is kind of normal human behavior. It is everywhere, and has been historically. Putting it like it's just 'labels for significant things' and then 'normal', and that these things would stand far enough apart to actually make a clear distinction without dismissing people in between is pretty much just wishful thinking. There's way too many things and even more combinations of then. It's gotten so complicated and convoluted only because it is that way. Wishing for a binary clarity in a complex world.
