That's ultimately a question of determinism, free will and whether it counts as "being an asshole" if you literally can't behave otherwise in cases highlighted as the reason.
For example, when a person with PDA doesn't do something especially when asked to, is it being an asshole?
Or when a narcissistic person refused to do anything that implies they've done something wrong before, and does the opposite maybe?
Or when a person with ADHD doesn't behave the way it's convenient for people around them?
Most people who called me an asshole in my life refused to understand that I don't want their social dynamics and discourses, I just want to discuss the particular question, literally. Not as part of finding some in-group and saying bad things towards some out-group, but literally to clarify the specific question. Well, and also some of them demanded respect they didn't deserve. That is, they were assholes, but I'm not sure you would agree, because you are likely not autistic and won't understand me.
I also have been rather hostile in situations making me recall my past wounds. Maybe I was an asshole, and maybe the other person could have been more considerate.
This is all subjective, the situation here is that from the description she clearly perceived what others said and did not as intended to be perceived. Case closed.
