By popular request, here is Umberto Ecco's essay UR-FASCISM, published in 1995.
In this essay, he talks about living in Fascist Italy as a child, growing up under that system during the Second World War. Then he details 14 qualities that define Fascist movements, regardless of the time and place they began.
It's a powerful and relevant essay. Many -- MANY -- of the 14 qualities he identifies exist in the MAGA cult, and I can see that a lot of them existed in the Astroturfed Tea Party movement from a few years ago. There's not a whole lot of daylight between the Republican Party in 2020 and the Fascist movements of the 20th and now 21st centuries. Not all Republicans are Fascists, but all Fascists are *definitely* Republican.
