Yeah, more violent things have happened. We humans are a bit odd that way. A high, studs-up tackle that breaks a player's leg will draw a red card and 3 game suspension. Then everybody goes about their business again.
But a more or less harmless bite to the arm will draw a 7 game (or more) suspension and universal revulsion. I guess the tackle is seen as part of the game, whereas a bite isn't?
It has been said that man is a rational animal. All my life I have been searching for evidence which could support this.
