I watch them and also do watch the killing parts if they are part of nature. For example, the lion hunting down a gazelle...that I'll watch. It's part of their life.
But one scene from a documentary back in the early 80's has stuck in my memory and I get so sad every time I think of it. It was a documentary about the baby heal hunt and showed men clubbing baby seals. I will never forget the mother seals trying to hard to get to their babies and save them, but were being forced back by the men and had to watch their babies be clubbed to death. That stuff I can't watch anymore.

That one scene from my early childhood is what turned me off of fur. I remember my mom having a mink coat when I was very little and how I loved to wear it when I walked out to the end of the driveway to get the paper on Sunday mornings. After seeing that, I wouldn't wear it anymore. It just made me sad.
