Chapter 17 asks if the logical fallacy called reductio ad hitlerum has a practical social application when I consider my own weaknesses and selfish tendencies. Chapter 18 is about looking for the imago dei in developing subcultures. It asks us to find the best in others, even while acknowledging the worst in ourselves. This has application to me as an individual, but also it applies to my worldview and my own culture. Is this the equivalent of Jewish jokes by Jewish people? Is this a helpful way to navigate relationships in our polarized world?
As a practice of this discipline: Can you name something, which is problematic about your own worldview, or the group with which you primarily identify? Can you name something beautiful and positive about a religious, non-religious group or political party with whom you disagree?
