You call me hyperbolic and tell me to calm down, then follow it up by swearing, insulting me and using hyperbolic rhetoric yourself. I'm not being hyperbolic, though, and your rhetoric makes me think you already realize that. I'm going to assume you're arguing in good faith, however, because otherwise I might as well not reply at all.

You think someone is evil, so now violence against them is okay. What happens when someone else thinks you are evil? Such as when you attack someone in the street for insulting you? If your answer is that most people would agree with you, there's the mob rule issue again - what happens when you're in a crowd that doesn't agree with you, or just around a couple of people who disagree and are stronger than you? Even the law tends to permit a certain amount of violence in defence of yours or another's safety, so odds are good even the police wouldn't be on your side, if they're doing their job.

There's also, again, the issue that someone you are too pussy to attack gets to have a lot more freedom of speech than someone you do.

At least you don't directly oppose the law, I suppose. I have no personal feelings on whatshisname being punched, but I am never going to endorse physical violence as a response to insults. Lastly, if you want your violence to make a "positive difference" other than giving you the warm fuzzies, the only way you're actually going to silence anybody is to kill them. Punching one of these people in the jaw is only going to give them a bunch of press.
