The Wormeaters won't be fighting, although they will start it.
They will weasel their way back into power and use the goonsquads to dominate us.
Liberals will just be the Kapos with the armbands, pointing out to the Jackboots who to take away and who to shoot on the spot.
Conservatives devoted to law and order will go to the camps quietly, at least at first, since they have property and families to protect and care for and favor quiet stability and fear the anarchy that comes with resistance.
They will go because they don't believe it can happen to them, and because they will cleave to their belief that it's all a mistake and as soon as they get word to someone it will all be cleared up.
Just as so many Russians went to the Gulag convinced that if they could only get word to Uncle Joe, it would all be cleared up, when Uncle Joe ordered them there in the first place.
