Put simply, our liberal democratic republic can’t be sustained if we all believe ourselves to be obviously on the side of the angels and always in an existential struggle against the forces of evil. In 2020, we should resolve to be less self-righteous and less scornful. We need more public figures to recognize their own limitations and the merits of their opponents. And we need voters, reporters, producers, and editors—those with the power to decide who gets the public stage—to prioritize civility.
