But...but....the Nazi's drove the communists out of Germany. You can't have two totalitarian regimes governing the same people? If the Republicans are the Nazi's and the Democrat party the communists then what's about to happen?

The Democrats are indeed communist and are calling the Republicans Nazis but the republicans are not nazis and are not responding as such. The question is how, in a free country, do you purge socialism from the political ranks. Democrats lie when they take the oath to protect the Constitution because they are socialists and socialism cannot be supported in America as long as the Constitution is being upheld.
Americanism is about the individual not about the collective and the good of all. It is impossible for anyone, especially government, to know what is for the good of all.

The Republicans are still trying to use reason and logic and appeal to the courts for due process and upholding of the law. But something is wrong with the courts and it is the final institution of appeal.
The courts seem to be protecting corruption.

There are a few big players driving it all. Making sure they get a pushback - a resistance. The communist democrats are trying to elicit violence. They have recruited most of the institutions as allies and the big corporations are also getting on board. The MSM, social media, the banking industry, the military, the intelligence community, even RINOs, Corporate America. They are almost all on board.
The CCP may be behind it, they are definitely contributing to the cultural erosion and weakening of America. But there are also internal players, such as Soros and Obama working to "fundamentally transform" America. The ACLU is on board and no longer seems concerned with individual civil liberties.

I think it has reached the point where to resolve this the socialists need to be purged from politics. The longer they are allowed to continue the more force it will take and the more patriotic Americans will be called Nazi's. In reality, a free market society of liberty and freedom will also oppose socialism in any form. Just because the progressive Democrat party is now socialist and has been overtaken by the communists doesn't mean that Republicans or conservatives or libertarians or classical liberals and the rest of America are Nazis.

How about Globalism? There are clear similarities between the Nazi party and how the democratic party in the USA is today. Both believe only they fully understand the world and what is important, staggering arrogance and sense of superiority, a belief they will save the world and make it a better place. Refusal to listen, debate and discuss. A determination to change and deal with those who do not agree with them. Vilification of an identified group to give themselves a shared target. the closing down and destruction of that group by removing their voice.
Poignant recordings from those who survive the holocaust describe how they initially were obliged to wear the star of David but thought they'd go along with it, pacify the haters, it was temporary and it would all work out. The average German got swept along in the rhetoric, turned a blind eye.
Many of the more centre minded democrats are behaving similarly today, they sat idly by whilst the elected president was constantly attacked and eventually silenced and removed and they watched silently as the democratic election process was stolen and abused.
The next step is likely to be they will strive to reduce and eventually remove private firearms before making republicans and particularly Trump supporters a targeted public terrorist group. Guilty individuals will be identified via previous social media comments, tracked and traced to have their bank accounts raided and jobs and homes taken before being locked up as enemies of the 'people'.
Millions of Americans will happily stand by and watch that happen. The Nazis were just trying to save the world, make the planet a better place and the majority fell for their message, nothing is different and those standing idly by just might be you and I.

..."Surely you don’t believe that the average non-political German soldier understood what his government was having him do to his fellow citizens before & during World War II?"...
Ah...yes they did. Just because they were nonpolitical and didn't care, doesn't mean they didn't know...
But lets use your same idea on the other side :
..."Surely you don’t believe that the average non-political Russian Red Army soldier understood what his government was having him do to his fellow comrade before & during World War II?"...
Yeah... they knew... just wouldn't dare say anything (or they ended up in a gulag).
Same goes for the woke. Exact same principles and ideology, but without the snappy uniforms. If I have to live under their shitty neo-socialist dystopia, the uniforms better be uber awesome for me to overlook the mass genocide!.

It's called Democracy. Majority rule. The only problem is that, through media manipulation, a few elites are controlling the thoughts of most people which is squeezing others out of having any say in anything.
Our Theocracy-elements (rules in our Constitution that don't care about Majority opinions, such as how the majority cannot vote to enslave minorities any more)
that weave through our Governmental System were designed to prevent this out-of-control democratic tyranny, but unfortunately our Supreme Court has abandoned their duties to allow stolen elections and cessation of free speech at the hands of the Media Oligarchs AND the Majority.
