I don't see an issue with Ulrich's behavior here. Calling somebody an idiot after being called "a terrorist" seems rather fair. Being a somebody, of course he is going to be the center of attention, not the dozens of nobodies annoying him into reacting like that.

Nobodies like you, who have no name, who have a disposable identity, who get to accuse people of misdemeanor online. You are not a decent person, that's for sure.
