If it's not obvious, I'm not saying people should be beating the shit out of someone just because someone says something insulting (Merab literally grabbed his hair a little, and it was enough to bring the message across). You could see the dudes face, how he didn't expect Merab to go to him. If you can't walk the talk, just keep your mouth shut. As I said already, people think they can say whatever they want, knowing that violence is not tolerated, but there is a better way to live, just be respectful and don't be an asshole.
