Individuals who voted for Trump don’t necessarily want to throw away a social contract. Many of them do support societal norms, albeit different ones. And some don’t even think in these terms; they are more motivated by other factors.
Along with many, I think their collective actions point in a direction that (a) undermines democratic rule and (b) enables Trump’s corruption, but they seem to be relatively unaware or disagree with such effects.
Many of them think Trump will combat one some types of corruption (the “deep state”).
Overall, I’m more inclined to think many/most Trump supporters have reasonable core values, especially at the individual and family levels, but due to their information sources and mental processing, their overall choices don’t bode well for us, together. The biggest breakdown I think has to do with epistemic values: how does one find truth.
I don’t think most people, of any party, have the individual ability and discipline to make sense of a modern world in a rational, scientific manner. This isn’t something easily achieved, after all.
About me: I strive to not “blame” individuals in the traditional sense, because I reject free will as a meaningful concept. (Roll back the clock and a person will the behave the same in a deterministic universe. And if the universe has intrinsic randomness, we can’t ascribe free will to that randomness.)
So instead of blaming individuals, I focus on systems and their statistical effects.
