The army eventually restored order by defeating the Communists and murdering Luxemburg and Liebknecht. In January 1919 an election was held, but no one gained a majority and there was no consensus. These forces would keep fighting for years, and Germany would remain divided and confused until 1933, when a wild-eyed vagabond from Austria would end the confusion by outlawing all dissent, and then the real troubles would begin [Metaxas in Bonhoeffer, 34].
Hitler’s rise to power and the eventual condemnation of all dissent is why true democracy is of great value. It is good to have the freedom to disagree politically. Very good. An ideology that outlaws every other ideology leads to tyrants and massacre on the human political level. We humans are too corrupt to be above accountability. If anything, this is a reason for American Democrats and Republicans to be thankful for one another.
