Well, to address your curiosity directly: I think that men who make their careers out of being hammers see an awful lot of nails around them, if you take my meaning. More specifically, "the gospel of the furher" is swooning language, so I think the General is being less than objective in his assessment.
My bottom line is that a fascist wants political domination and a bullying CEO type wants his butt kissed and lackeys saying yes sir, but not much more. Ex-Pres Trump (God, I love the Ex part) is unequivocally in the latter, hence not a fascist in word or deed, pretty much by definition.
Fascism and bullying look very much alike. It's the motivation, and consequent action, that separates them. I look at what a fascist would do in a given scenario, and what a bully would do. To my eye, when the dust settled, Trump was 100% in the latter category. The threat he posed was real, but not fascist. A fascist would not have let the unprecedented opportunity on Jan 6 limp away. A fascist would not beg the courts to see things his way. A fascist would not sulk away to Mar-a-Largo on Inauguration Day.
Trump was several levels too weak to ever even approach fascism. That's why, for all the swooning and hyperbolic rhetoric, neither he nor his ever-dwindling followers sported armbands with a black T on them and made a serious run at power. They don't even want it.
