I don't think anything is universally benign. If you get right down to it the woods are not benign. All those tall rotting trees just waiting for a gust of wind to come down on someone. That is even without consideration of the animal life. Most interactions with large animals are situational. While most people consider deer benign, deer kill more humans than any other woodland animal. The zapping thing while unpleasant, is preferable to having my head ripped off. So maybe BF thinks they are doing us a favor if they feel they need to zap because we are a problem. In my case I asked one to stop, and it did. I thought that was a good sign. Of course the BF may not have understood a thing I said, and was incredulous that I was so numb that I did not know I was being zapped.
