"Authoritarian and anti-democratic are bad enough."
I'd add un-American to that list.
Remember, we aren't talking about "the current US Republican Party", we are talking about the mostly Trump-lead ultra conservative, far Right portion of that party.
The drooling core of the MAGA-cult aren't fascist themselves, being for the most part entirely too stupid to understand the concept. Rather, they are just wannabe quislings.
It's Trump and his inner circle of sycophants that are attempting to become fascist rulers.
