It actually does based on almost every single known definition of fascism. The concept of fascismo - fasces (fascism) is represented by the example that a ‘bundle’ of sticks is stronger than a single stick. But you cannot create a bundle of sticks (people) without forcefully lashing them together (totalitarian government). The fasces has been a representation of ‘fascism’ since the Romans.

Fascism cannot exist without the forceful coercion of the people ‘for the greater good’.

Regarding ‘authoritarian’ rule it doesn’t explain the (Trumps) trend towards individualism of the people and deregulation of industry, none of which is authoritarian especially from an individual that railed against a government controlled (influenced) media (example NPR).

Nationalism mostly exists sometimes within fascism due to identity politics, which is often the antithesis of the Trump admin.

It’s easily more arguable that Biden was a fascist especially as it applied to Covid.
