You cannot be naïve about evil. You cannot be naïve to the reality that there are human beings and human situations which have totally identified with the dark side of reality. They are malicious. Realism teaches you to put up appropriate boundaries so that people can't do any more evil than possible. But that doesn't mean you do evil back to them.
Richard RohrChristianity is a lifestyle - a way of being in the world that is simple, non-violent, shared, and loving. However, we made it into an established "religion" (and all that goes with that) and avoided the lifestyle change itself. One could be warlike, greedy, racist, selfish, and vain in most of Christian history, and still believe that Jesus is one's "personal Lord and Savior" . . . The world has no time for such silliness anymore. The suffering on Earth is too great.
