Walk out and leave the one who insulted you in charge of the situation? That's called letting him get away with it. It's called cowardice. If someone insults or disrespects me or my loved ones, I have an absolute right to lay hands on them, if that's what it takes to teach them respect.

Or are you one of those poor fools who thinks violence solves nothing? Who believes that Putin will be stopped by anything other than naked force?
