I would say yes, just because that is the primary reason I don't like watching it. If there was a fight in the street, I would watch to ensure my safety, as well as ensuring that they are not murdering each other. However, I get no enjoyment out of it, and I don't like watching people get hurt.
However, I do understand it is a sport. I'm sure if I got into fighting, I might appreciate it as a sport a little more, and see past the brutality.
