There needs to be an Amendment added to the constitution. Communism and all it’s forms shall be banned. It has no place in a glorious creation of a truly civilized country that if fulfilled we could have a country that’s as close to perfect as possible. Communism is anathema to freedom and liberty.
I think Hungary was on the right track by banning Soros NGOs and removing “Studies” programs from universities. That seems to be the root of a lot of the disruption to civilization these days.
No amendment needed. Look it up: the Constitution guarantees a republican form of government for each state.
