DerScheisser is a great meme sub if you just want to dunk on Wehraboos and Neonazis, but is still predominantly shitlib. It literally bans anyone who says anything positive about the USSR beyond "they killed Nazis". Really goes to show you that Liberals would go through the Weimar motions that put the Nazis in power in the first place again in a heartbeat so long as they stop the commies in the process.
EDIT: Late link.
Also also. And i cannot stress this enough. The 1918 post revolutionary SDPgovernment were not elected and did not gain power through popular legitimacy. The uprisings in 1918 was led by workers, and none of their leaders or groups pointed to the democrats , indeed the social democratic leadership explicitly opposed both revolutionary worker groups and the occupation of the Reichstag. However Ebert was appointed chancellor by the sitting government as a sort of compromise, and immediately went to work subverting impromptu workers groups and revolutionary movements
The Council of the People's Deputies was a sham from the start.
