While bullying is a world wide thing, the places Ive been, the US was the worst, by far.
I lived in 3 different states went to 3 different schools. this was something like 20 years ago..
Never ever in my life encountered such of assholes like I did in florida.
I was not a big kid, but didnt let any idiot try to bully me, sure some fuckers tried to though. Anywyas, theres something about it in the USm and its horrible, I cant imagine having a son having to go through elementary highschool and colleg being bullied, its a horrible thing.
IMO, get your kids into MArts as soon as they can, boxing kick boxing wrestling bjj, some full contact sports. SD is really usefull in those stages of their lifes, later on, not so much, but being respected in school can make your sons life a shit ton better, they spend like 20+ ears at school, they better have a good time there.
