Susan Kehoe is a staunch opponent of bear hunts in New Jersey, and her activism has put her at odds with authorities a number of times. But apparently she's just as opposed to bear-on-bear violence. She recently uploaded this video to YouTube of two black bears getting rough with each other, until she stomped into the woods after them with a firm, "Stop it!" And, amazingly enough, they do. How long this cease-fire lasted, no one knows. And as a number of commenters pointed out, it's just downright dangerous to potentially antagonize a bear, never mind the possibility of them losing their fear of humans.
