We need to enter the conversation willing to be wrong, willing to admit the limits of our own knowledge, willing to reconsider our evidence, sources, and premises. That is self-skepticism.

Arguments for slavery weren't pragmatic or ethical discussions about the realities of slavery; they were assertions about abstract identities (The Slave, The Slave Owner, The Abolitionist) and performances of loyalty to the South. They were demagoguery.

Partisans will try to appeal to the notion that political arguments are really about which group is better in order to dismiss criticism of their group. We might think that we can refute criticism by pointing out that 'the other party does the same thing too.' But whether the other party does it too is relevant only if we're arguing about which party is better, not which policies are better.

Demagoguery is powerfully reduced when it stops getting people elected, and that usually happens because of in-group policing. Similarly, when it isn't profitable for a media outlet to engage in demagoguery, it won't, and that happens when its target market declines to put up with it. Individual demagogues are best stopped by in-group condemnation, and particular strains of demagoguery are generally ended by public shaming.

The underlying problem is that we aren't arguing policies; we're arguing about identities, and therefore compromise is never considered a principled realization that they might have some legitimate concerns. It is, at best, a Machiavellian strategy forced on us by the bad group.
