“Kids can’t defend themselves nowadays. If they do, then they are the ones’ to get kicked out”
Absolutely correct. I’ve told my kids they are free to defend themselves regardless of the consequences. Of course we homeschool now but the rule stood while they were in public.
At my kids school they will call the police and have a kid arrested and expelled even if they are defending themselves. My kid hold a black belt and has got quite strong going into his senior year. At 5-10 he doesn’t get messed with anymore.
