"Shut up, I am right"

I'm sure it happens in other countries too, but I find it highly obnoxious and gross that ANY confrontation in Italy is a total idiotic fight. Topic is irrelevant. Politics, sports, anything. Participants do EVERYTHING to prevent opposed viewers to have their say. Most common practice is to talk over the other, as if both chess players would move at the same time. There's no way to witness sensate discussions, therefore no interest whatsoever in following awful, miserable cacophony. Loud, stupid, useless.
