The kicking was a threat. It was the threat of a man against a woman and children. I didn't say he tried to kill them or that he physically harmed them (and kicking a car is nothing compared to trying to run someone over), but it was a threat. How is kicking someone's car when they're in it not threatening behaviour? Autism is not an excuse for making threats.
Finding it pretty funny that as always, a bunch of do-gooders (let me guess - mothers of autistic sons? Or maybe you just met someone once and now it's your pet cause) defend the violent autistic man against the online accusations of someone who is also not neurotypical, for being so discriminatory and not knowing what it's like. Sorry, I wasn't wearing my badge?
She definitely should have left it, I'm not arguing that. But not because he has autism, because she should have anyway.
