> Parents won't force their kids to continue to be around others they dislike

Ha, you would be surprised. Parents will totally force kids to be around people they dislike. I mean my parents knew that I was bullied in my private, free association school. Even after one asshole pulled a knife on me and the school wouldn’t do a thing because he was from a rich family in my small town, they still decided to kept me in there because “it has good academic level/learning to deal with these people is good/kids will be kids/<insert other bullshit excuse>”.

But hey, maybe you are right and free association is good. After all they kicked me out because of absenteeism when I decided to bail out of school because it was living hell.
