Has the violence in professional sports caused you to stop watching?

I enjoy baseball currently, but I stopped watching football several years ago because it was too upsetting to watch the guys get hurt, some tragically. Even baseball has its dangers, to players and fans both, and I understand that sports in general can be violent, but has the violence gone too far, and is it preventable? Have you changed your sports-watching habits due to the violence, and if so, in what way(s)?
