The Next Civil War

The existential conflicts that drove us to war in 1860 are the same as the existential conflicts dividing us today. Slavery has been abolished, thankfully, but nothing else has changed.
The conflict that divides us works itself out in various ways: an emotional dispute over our highest ideals, a dispute over philosophical preferences, a cosmological dispute over the true nature of man, a dispute over the social roles we should adopt for a greater society, or a political dispute over the value of political discipline versus political flexibility.
It does not matter how you frame the argument. It is always the same argument!
This singular dispute is ongoing. In more enlightened times, this dispute was worked out quietly, scholarly, and without hostility. Today, not so much.
Today the conflict shows up as differences in emphasis, identity, and interpretation, and it has intensified into a sectarian conflict.
You call yourselves Democrats or Republicans, but insofar as you have turned a blind eye to your opposites, you are only anti-American.
Proposed: Let us learn, once again, how to accept and get along with our neighbors.
