Several good points here.
You actually have to have an existing Left to have Fascism. We don’t have that in USA.
Like Germany in early last century, USA has the veneer of a high civilization but underneath there is a huge swath of ugliness. Trump and the red hats have ripped off that veneer as Hitler did in that country.
Liberal cancel culture contributed to the rise of the red hats by shutting down discussion. Example: puberty blockers.
