It always frustrates me a little when people look at a problem and say "that's just how things are." Here it's the thing about humans being violent. In a trivial sense, that is true, but I think that obfuscates that in most situations violence has a set of politically-meaningful sources, even if it's personal violence. Being beaten as a child, being forced into crime, being taught that violence is appropriate to protect your "pride", the Other being dehumanized, the list goes on.
