Polarization, Reconciliation, and Dialog

Twenty years ago, we were noting that the U.S. seemed ideologically divided over “blue state/red state” lines.  Now those difference pale in comparison to the polarization that accompanies doubt and suspicion over “fake news,” and we seem to lack a shared sense of reality from which differing political positions can be weighed and compared.  Topics like abortion and same-sex unions have been controversial for years, but the rise of social media “filter bubbles” have permitted us to restrict our communication to like-minded people and paint those who oppose us as an unapproachable “enemy.” Is this our fate? Can faith and/or philosophy help heal a deeply polarized nation? How can people of faith speak meaningfully about contentious issues with secular society?
