Ive made this argument before. If you sign up for the sport, you know full well what you are getting into at this day in age. Dont want concussions? dont play contact sports. why should physicallity get taken out of a sport that is used for entertainment purposes? If you cant hack it retire. The players arent being FORCED to play. They arent being FORCED to fight each other. You are signing up to play the sport knowing all of the repercussions of the sport now. including head trauma. Take care of yourself first imo, but again its not like these guys HAVE to play hockey.
is the point of hockey to fight? no. the point of hockey is to skate around, shoot pucks, and score goals. the Prime Directive of Hockey isn't "punch somebody in the face." organized sports like football, basketball, and baseball don't have a primary objective of "injure other people."
fighting is a product of the attitudes that the people who played hockey took towards the sport, and many other things. but it's not an inherent component of the sport. with that in mind, justifying fighting considering the pain and suffering that people like Montador, Boogaard, Carcillo, and Boynton went through is very incredibly difficult.
