"Americans don't like hockey because it's too violent."

Yeah right. When was the last time you saw a bench clearing brawl in a NHL hockey game? As you said, that's something that happens all too frequently in MLB. How sad is it to see non-player personnel involved? How sad is it to see the guys in the bullpen run in?

The penalties for leaving the bench or penalty box is more than a simple ejection. There's suspensions, fines and team fines involved. If MLB wants to eliminate the same type thing they'll likewise impose some serious consequences on the players and teams.
