Brawls in Sports?

I am an avid sports enthusiast. I watch everything from high school sports to the professional level. I don't understand why things are allowed to get so out of hand when it comes to professional sports..........specifically hockey. In an article located on Fox Sports there is some debate as to whether or not fighting still belongs in the NHL. Personally, I feel that it is way over the top. Why is this something that is acceptable in hockey, but not in any other organized sport? There is no need for this type of violence within the realm of hockey. It has become progressively worse and tensions continue to escalate on the ice. Maybe it's time to put a stop to this and make the time spent on the ice more about hockey and less about the fights that break out.
