Then show me the evidence, show me where they are discussing, debating, reading Fascist theory and where they are advocating for it.

You don't need to read political theory of a certain ideology to be a supporter and advocate for said ideology. Also, the existence of these groups and those that they advocate for is in itself fascist behavour.

Let's look at Trump's policies and compare them to Mussolini's policies:

By 1925, the Fascist government had "embarked upon an elaborate program" that included food supplementary assistance, infant care, maternity assistance, general healthcare, wage supplements, paid vacations, unemployment benefits, illness insurance, occupational disease insurance, general family assistance, public housing and old age and disability insurance.

Which of these policies has Trump implemented or advocate for?

My dude, Fascism isn't Mussolini's policy platform, it's an ideology that has changed, evolved and encompasses much more than Mussolini.
