Political debate, even vigorous debate, is a healthy thing for a democracy. But to question the integrity, patriotism, and even the faith of those with whom we disagree is destructive to democratic discourse. And to threaten or even imply the possibility of violence toward those whose politics or worldview differs from ours is a sign of moral danger and, indeed, a sign of democracy’s unraveling.

This fundamental disrespect in the political debate has harmed the public square.
