Thing is that it isn't inevitable that you'll get a kicking if you stand up to a bully.
One of the primary problems is that people shit out kids with no plan for how they're going to raise those kids. Winging it, particularly when raising someone to be a productive member of society, is never a great idea.
Send your kid to martial arts... doesn't matter which one (aside from Aikido... that'd be retarded) from the time you feel he can take instruction.
Sent my loon to karate from the age of about 5, he's now 11, so for more than half his life he's been learning how to swing a punch or a kick. Before he was even born we had a plan in place for raising him to be self sufficient, able to take care of himself, and the last kid bullies would want to target, because we all know that kids are fucking arseholes to each other. Any sign of weakness and they're like a pack of wolves.
He's close to black belt in Karate... he'd be black belt now, but he's restarted at white belt twice in moving schools, when he gets that he moves on to Jiu Jitsu, and when he has a black belt in that he moves on to Krav Maga.
Right now he has a punch that would knock out an adult, and that isn't even a slight exaggeration. He's fucking brutal,
A couple months ago he moved up to middle school, which is when we figured kids of that age... about 11... would start trying to assert themselves over weaker kids. Sure enough a couple of the wee cunts tried bullying him. He gave them fair warning, but they took his unwillingness to push back as exactly the kind of weakness they were looking for. He's been told to avoid fighting unless it's necessary, and that's what he was trying to do. Eventually the name calling turned into pushes, and finally they tried to smash his iPhone, at which point he figured it was time to push back.
He blootered one of them clean on the beak... by all accounts fairly bursting this kid's nose all over his face... and the other wannabe bully took off before he got the same. He hasn't been bothered since, and apparently the kids are still talking about the puddles of blood this kid left in the bathroom at school
The point is that if we hadn't raised a kid who can take care of his own shit he'd be at the mercy of those two little cunts right now... he'd be months into a bullying campaign that the school, let's be honest, would do fuck all to prevent.. "Zero tolerance policy" or not.
If you have a kid, I don't care if it's a boy or a girl, big or small, send that kid to boxing, karate... anything... just so long as you get that kid in the frame of mind that he or she is never going to be a victim of the kind of little prick who's going to seek out the weak and make their lives a misery.
Fit happens when everyone sends their kids to karate and the bullies have black belts too?
