Being involved in education means I’m always in conversations about bullying. Hell, being on the internet means there are always conversations about bullying. My viewpoint is apparently somewhat radical – I don’t think the bullies are the problem that need to be addressed. Here’s why: there will always be assholes in the world. There will always be people who project their own insecurities, or have a need for power, or what have you. Always. You cannot stop them.
What you can do is teach others the how and why of standing up for themselves.
Some background slash an anecdote: my dad wrestled us as children. We were never afraid of having hands laid upon us, the only thing was to figure out how to react. While I was slight of figure and certainly an outcast, I never dealt with bullying. This was not because there were no bullies, but because I was not afraid of a fight. Sure, the other party might win but I would inflict some major damage on my way down (which is, incidentally, how I also play chess).
I could ramble on and on about this. But basically, it boils down to people trying to end bullying are looking at the finger instead of what it’s pointing at.
