Obvious caveat, me being European, but I am not so sure MAGA has the "foot troops" to make a full on fascism happen. January 6th was a bunch of rag-tag fringe people running around in costumes and how far the existing state apparatus (mainly the police) will go along with it is hard to say.
For sure it will embolden the already hard-on fascists, but the historical Nazis had their own shock troopers (and many of them) to scare the majority into compliance and look the other way when really bad stuff happened. This was not the existing police force, but a paramilitary group that later became the SS. Other fascist regimes had similar large paramilitary groups to back them up.
I know this goes against the election strategy of scaring people to vote for the democrats no matter what (which is probably still what most people should do for tactical reasons), but if we are talking about "harsh truth", I think this is worth mentioning.
