Ur-Fascism by Umberto Eco (1995)
What an insightful piece.  It is interwoven with Eco's experience as a kid in Fascist Italy, but written 50 years later.  At the end is a little listicle of typical characteristics of a Fascist movement, with a careful indication that not all will be present.Being written in 1995, the training set is independent of the test set, and one is thus free to find parallels in the current moment:"Irrationalism also depends on the cult of action for action’s sake. Action being beautiful in itself, it must be taken before, or without, any previous reflection. Thinking is a form of emasculation.""Ur-Fascism grows up and seeks for consensus by exploiting and exacerbating the natural fear of difference. The first appeal of a fascist or prematurely fascist movement is an appeal against the intruders.""To people who feel deprived of a clear social identity, Ur-Fascism says that their only privilege is the most common one, to be born in the same country. This is the origin of nationalism."
