There’s neither even a rhyme nor reason to Trump’s fascism (or to fascism in general). But it does correlate with the observation that they are fantasists. They do things out of whim and emotions, disregarding expert advice and opinions. Any promulgation of fascism will eventually lead to its own downfall, because they live in a fantasy world where they believe that their will alone could shape reality; ignoring the basic common sense that reality could never be altered to one’s desires.
