I don't disagree with you and I agree that the stereotype of autistic people as lacking empathy is harmful and generally untrue.

HOWEVER - the person I was replying to was mentioning them being hurt by the behaviors, and that signals a lack of empathy from the individual doing thise actions.

Even apart from behavioral disorders, there's comorbidities -- autism is comorbid with ADHD and ADHD is highly comorbid with a lot of conduct disorders and personality disorders.

So it could be any of that. But my basic point is that for the person I'm replying to all of this complexity simplifies if you instead focus on the effect of the other person's behaviors on you. That's what you have control over.
