But, but, Brovo! Eye for an eye!!!!! EYE FOR AN EEEEEYE!!!!!!!!!!!!!!!!!!!!!!!!!

But in all seriousness, the only real way to stop violence is WITH violence in some capacity. Not saying you need to go fucking apeshit ballistic, but you need to physically fight back, not just scorn the aggressor and "feel bad" for the person said aggressor attacked. Know what that does? It allows the aggressor to keep BEING an aggressor, they will NEVER change just because someone sent them a letter or message that is filled with emotionally charged words. Words can only stop something BEFORE it happens, they can't stop it from happening as it happens.
