Among other things the huge parallel that stood out to me is that they push for all this racist fascist crap while wrapping themselves in what most people would consider the most revered icons of our nation. The things that we always used to use to adorn the parts of our nation we are proud of, at least until maga coopted many of them. The flag, George Washington, etc etc.
This is exactly what I think is happening. The result of R destroying itself is somehow turning out to be no political home for progressives and left of them in US politics.
