Yeah, as a neurodivergent person too, I also faced bullying and it was fucking horrible.
I can see bullying still being an issue on the first generation of people living in a socialist society, but as the individualistic ideology starts fading in favor of a more collective one, it will probably become much less of an issue.
That being said, it's probably a good idea for said society to actually teach people how to be parents, teach professionals how to deal with bullying at school, etc. I always found weird how school never teaches kids this stuff in my country. If we learned at some point in the educational system how to parent, it would probably lead to a much healthier family relationships in general on society.
There's also other stuff that can and should be done, like teaching about neurodivergent people, about limits, respect, empathy, etc.
One thing is for certain tho, I cannot see bullying stopping under capitalism.
CW: bullying case that lead to death
Just recently a 13 year old autistic boy died from health complications after being physically bullied in a school in the state of São Paulo here in Brasil and not receiving the proper medical care after being dismissed multiple times by medical professionals that only prescribed some medication. There are videos of the kid crying in pain and having difficulty breathing. This case is utterly fucking revolting and shows how deep bullying is ingrained in our society, specially since the school knew and did absolutely nothing, there are reports of parents contacting the directors on multiple occasions about bullying happening in that school, and nothing ever happened. The toilet he was beaten in was called "the toilet of death" for fuck's sake.
