@wdlindsy interesting. We might disagree here. The author in my opinion doesn't give the concept more power rather they dismiss concept while literally using definitionally fascist characteristics to describe what they call not fascism.
Also, while the press and lay population may use a more flexible variety of the word, people like Stephen Miller are using the textbook definition (if such a thing exists, strictly speaking), though I'd argue it's an evolution best described as neo fascism.
