I'm the most left leaning person I know and am involved in local politics. I'm pretty sure most of my cohort opposes forfeiting our sovereignty to financiers.
But I'd say outrage, vs fear, is my prime motivator.
FWIW I've adopted Jonathan Haidt's Moral Foundations Theory, until something better comes along. None of the personality traits are correct or incorrect. They just are. I'm just trying to understand other people better, esp those I disagree with.
Edit, TMI warning:
My SO voted for Trump. And about 1/2 my family are #MAGA. We largely have the same values, culture, upbringing. So it's fascinating to me how we reach different conclusions. I was truly surprised to learn about fear, anxiety, and so forth.
My SO's prime motivator is fear, which she proclaims openly. Whereas I have near zero fear response. That difference is the basis for most of our quarrels. And, frankly, I just didn't grok the difference, so was being quite the knucklehead.
Ya, labels suck. I'm "liberal" in the sense that I support whatever works and embrace change. Adam Smith, Marx, others all made some great points, many of which have been lost, but progress marches on and we must adapt.
