Empathy has a performative component to neurotypicals. If you are not acting as though you are empathizing, you have "no empathy" and are thus a strange form of psychopath. Actual psychopaths can pass the performative part of neurotypical empathy with flying colors because they are excellent maskers and mirrorers -- that is, of course, when they can be bothered to try at all.

And they see us as loud, pushy bulls in china shops who are unable to handle delicate affairs with any nuance, even if we're well-meaning.
