Imho one underappreciated element of the "reach out to conservatives" side is the belief that social closeness plus empathetic persuasion plus coming to common understanding of facts will not only help bring us together, but will help conservatives renounce Trumpism. But...

This view sees chaos and hyperbole of Trump and does not see trumpism as a coherent world view that existed before Trump and was reinforced and strengthened through his strategies. Trumpism is not a simple misunderstanding, or an unfortunate miscalculation based on a few lies.

It is a view of society ruled by hierarchy, a zero sum world where if you gain I lose. Boundaries and belonging are carefully policed, and people basically get what they deserve, so concept of "justice" is shrunken to individuals being punished for individual actions.

There's ++ research on this (just world hypothesis, social dominance orientation, etc) but I see it when I have conversations w people about apparently nonideological everyday issues. Sports refereeing. Giving away unused event tickets. HOA rules. Home improvement.

I'll also say you can see these views activated in many many liberals when you talk about public schools. Zero sum thinking and (firm yet polite) dominance orientation justifies school segregation in the minds of so many nice white parents.

If you understand trumpism as a latent authoritarianism present in most of us, but strong & dangerous in white people, then how do we fight it? I'd say better than focusing on transformation of hearts and minds, focus on building open, inclusive, public institutions of care.

Why? Because such efforts at inclusion and empowerment reduce thrall of private benefit and demonstrate that public good exists. Robust universal public services also can empower disempowered people. The concept of public health is inconsistent w zero sum thinking.
