So are you. There was the sordid history of the Spartakusbund in Berlin, converting it into a squalid hell-hole of debauchery, strikes, and rioting.
The question today is not democracy or dictatorship. The question that history has put on the agenda reads: bourgeois democracy or socialist democracy. For the dictatorship of the proletariat does not mean bombs, putsches, coups, riots, and anarchy, as the agents of capitalist profits deliberately and falsely claim. Rather, it means using all instruments of political power to achieve socialism, to expropriate the capitalist class, through and in accordance with the will of the revolutionary majority of the proletariat.
They were communists. Several of their leaders (notably Rosa Luxemburg) were of Jewish ethnicity (as was also true of the Russian revolution). The mass extermination of the middle class after the revolution in Russia and the attempted revolution in Berlin scared the Germans so badly that they fell into Hitler's arms.
" So are you. "
No, you just aren't going back far enough.
The intelligentsia of the late 19th and early 20th century took the idea of Survival of the Fittest (no, this is not a discussion of Darwin) and embraced it. They saw nothing wrong with the idea of helping to weed out the weak among society.
Then the socialists, communists, and fascists pounced on that idea and took it to another level, justifying mass killing and genocide.
But the truth still stands that even people in this country had no real problem with the concept of getting rid of the weak and unfit in society. This allowed them to turn a blind eye toward what was happening in many parts of the world. Teddy Roosevelt, certainly no communist, said, "Society has no business to permit degenerates to reproduce their kind." George Bernard Shaw believed that only eugenics could save mankind. Margaret Sanger started Planned Parenthood based on the concept of eugenics, abortion rights for convenience was a later addition for PP. All of these ideas were firmly in place before the pogroms and exterminations of the 20th century.
Of course Germans fell into Hitler's arms, but one of the reasons they did so was because of his views on the "Master Race", an extension of eugenics theories.
