Caporegime
You sound like a thoroughly unpleasant individual. It doesn't matter how irritating you find something you don't bury a hammer in someone's head. There are ways of dealing with your irritation that are much more socially acceptable.
The idea that it's some how even slightly explainable because of how the guy *might* have behaved is disgusting. You should be ashamed of yourself.
And you sound illiterate as you clearly can't read what I've written. Twice. Why should I be ashamed for understanding how people can be pushed to violence? Because I'm a nice chap I'll again reiterate for you that it is in no way the acceptable thing to do but I can understand how when you are forced to endure someone who goes against all your beliefs that in certain individuals it can lead to violence.
