Where did Reichs 4 through 8 go?
Sorry, “Ninth Reich” is a personal joke about hysteronics of those trying to prove the onset of great evil beyond rational/sensible proof.
I suppose Reichs 4 through 8 were FDR, Regan, Bush I, Clinton, and Bush II. One way or another there was some hysterical subgroup decrying each administration as the next Reich.
