My problem with fighting in hockey is not so much the fighting itself, but the plethora of rationalizations that are used. To me, fighting is reactionary, it's for entertainment and team cohesion. I just dislike when people start talking trying to make it much more than that, where it's a requirement otherwise your skilled players won't dare to do anything or there will be a free-for-all for cheapshots. These things just doesn't seem to have any support other than the anecdotal.
I'm not going to argue that fighting should be abolished. I just wish people would be comfortable saying "I like fighting because it's fun, and the team seem to feel good about it", instead of conjuring up horror stories where it's the only thing that'll keep Marner from being hospitalized on a consistent basis.
