Speaking as someone who was a teen in the 80's in the United States: The only way to stop a school bully (a person who has learned to use force for personal gain) is with a bigger "bully" (another stronger student, or an administrator who has more force). Therein lies the rub: Might makes right. There's no stable system of sheep because the most wolf-like of them will always emerge to take advantage of the others. You see this in behavior across species, there's like an "aggression equilibrium"; too many wolves result in too much bloodshed; too few and a single wolf obtains an outsize share of resources/social/reproductive capital, or what have you (and thus perpetuates their aggressive genes). Witness every communist system put into place so far: What was envisioned was a system of equals, but nature abhors a vacuum so what you end up getting is a bunch of people considered equals, and a dictator above them all.

And truly, I learned this lesson early on only because of bullying (towards me): The school administration did nothing. The teachers did nothing. I was left to fend for myself... and this is what I learned: If you screw up the courage to stand up to a bully ("display your readiness to use force"), they will often back down. In some cases they will ONLY back down if you resort to physicality (the proverbial "fist to the face"). I learned this lesson again and again- I've had my wrist broken by a bully, but at least he never messed with me again. And as an adult, I've applied this, not in the direct use of force but in the fact that your will is what counts- when fighting traffic tickets, it's you vs. the system.

It shouldn't be surprising that 100% of the bullies I knew (who because I'm a peaceable sort, I actually friended on FB years later) became Republicans. But some of them also became leaders in various things.

My main bully, however, was apparently a troubled sort himself, and ended up taking a shotgun to his own head in front of his family. Spent a week in the ICU before giving up the ghost. Before this happened, I randomly ran into him at a bar. I didn't recognize him at first because he had gained a lot of weight, but one look in the eyes (the eyes always contain the identity of the individual when nothing else does, for some reason) and he immediately said "Let me buy you a beer". I accepted.
