If they follow the Communist Manifesto, they would first murder/disappear/imprison their own sides' rabble rousers. As Commies know that those are the first people to create an opposition party after the opposition is exterminated.

So first Antifa, then the alphabet agencies will be forced to "prove out"--fight among themselves til a single winner stands, then they become the Stazi. After that it will be "reasonable leftists" like Bill Maher, Glenn Greenwold, Matt Taibi. then they will go after Trumpists by only allowing them certain jobs like janitors and garbagemen. Doctors will be told to not perform operations on you or give you fake pills in place of medication. This way they can just say medical issue when you die from using fake insulin or some other easily treatable issue. They will take your homes and give them to Communist Party members or some guy who just walked here from Guatemala.

Any more questions?
