People picked on me and physically bullied me in middle school...briefly. I ended up in the office twice for injuring students who picked on me back in sixth grade. They told me they would call the police the next time I hit someone (because the second time, they lost their front tooth), but by then my point was made. Nobody ever touched me or even said anything bad about me ever again. And I got respect.

I'm not nessecarily suggesting that violence is the answer but...okay, let's not bullshit, it is. If someone TOUCHES me, they receive a serious injury. All there is to it.
