I continue to find @interfluidity's notion of "fascism as triage"* a good way to understand the rise of the far-right in the US and globally. Fascism finds fertile soil where people have given up on the idea there's enough for all of us to live well together. Insofar as you are in a scarcity mindset, that's when us-vs-them becomes appealing.
