Polarization leaves very little room for reasonable discourse at the poles too. Pure tribalism doesn't care about reason unless that reason is in service of the identity and ideology of the tribe.

What if political discourse was focused on policy not identity and couched in terms of mutual interest instead of party affiliation? There would still be tensions, trade-offs, conflicts and political strategy at play but the discourse would be infinitely more reasonable.

I think this is what we mean when we talk about "center positions": a "value-based realism" that recognizes that society is nothing but the mutual alignment of values and interests. I don't understand why "common sense" has become so unpopular.
