The stuff you are preaching as the blunt reality is all opinion. You are not tough or wise because you think like that, nor am I weak for not "coming to realize' this. It is stronger to do what is right no matter what everyone else believes, not take the easy way out because everyone else does. If you are not willing to take loss, keep them penned. These predators belong here more than the chickens, and even most people, do.
If you really accepted your role in nature, you would not "take revenge" when people are eaten by other animals, and you would not create cities void of animals. There are predators that eat people, yet once a person is eating like nature intended, we eradicate the predators. Say what you will, I can not stop you, but we are meant to be eaten and have our population kept under control. We think that anywhere where we want to live should be free of all animals that eat flesh. That is not the way it is intended to be.
