Chapter 4, “The Anatomy of Fascism Denial”, tackles the remarkable reluctance and often flat-out refusal of reporters, pundits, politicians, and intellectuals – including many on “the Left” – to properly understand Trump and Trumpism through the lens of fascism (and even in some cases, as authoritarianism). I pay special attention to the dogged stubbornness of this denialism, which persisted even after Trump revealed his fascist essence (evident from the start to numerous serious observers) in bold strokes in 2020 and 2021. The chapter begins by documenting the denialism of mainstream Democratic politicians and the “liberal” corporate media. It then examines the curious denialism of intellectuals, academics, and European historians especially, tracking the extraordinary resistance of many university-based so-called fascism experts to properly identify Trump and Trumpism as fascist even as Trump: fanned a deadly pandemic that especially targeted the poor, non-white, old, and sick; deployed paramilitaries to repress civil and human rights protesters, threatened martial law in response to the George Floyd rebellion, and waged an open campaign to subvert and then nullify an American presidential election. Especially odd and disturbing was the fascism denialism of Leftists, many of whom responded to reasonable analyses of Trump and Trumpism as fascist with bitter mockery and a host of false narratives. Chapter 4 offers a detailed critique of this denialism. It is a study in intellectual, political, and moral failure.
