Reminds me of this from the NYT columnist David Brooks:

"Moderation is not an ideology; it is a way of being. It stands for humility of the head and ardor in the heart. When you listen to your neighbor, you see how many perspectives there are and you’re intellectually humble in the face of that pluralism. When you listen to your neighbor, you see that deep down we’re the same and you hunger to deepen that connection."

I say about that quote in my piece, https://medium.com/illumination-curated/can-we-please-all-find-the-space-within-which-to-breathe-the-same-air-and-agree-not-to-agree-6b6b2c8077ec

"In other words, moderation, regardless of where you fall on the political compass, allows the space to agree not to agree."
