I know that tons of highly morale persons wont agree with me, but actually I must agree to mentioned experiences, that if you get physically bullied, to fight back.
I ignored all kind of verbal and physical bullying, but if you bullied me physically, I punshed back. When I came in a new school with new classmates, that normally happened 1-2 times, and then people were done with it, and did not bully me physically anymore.
I can only recommend parents of aspie kids to sent them in some sport, that learn them responsible self-defense. On one side they get to train physical abilities, that most of us lack anyway, so nothing bad about traning that, and as well that as Aspergers many of us simply lack knowledge of social situation, in combination with naivity and being "a bit behind the peer" when it comes to the maturing. That simply makes as easy victims for all kind of people. So I dont like being fooled of, or to be part of an joke that I dont get, but at least when I actually get physically treated, so that its obvious that someone wants to do me a bad or is a bad person, I fight back without hesitation. I think it important, to teach a child the confidence to do so.
Always told my partner, that if our kids become as nerdy and weird, as I was, that I will sent them in some kind of self-defense course.
