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.
Nowadays, most western "leftists" at any given moment are well to the right of the 1920s SPD.
Given how the SPD originally split over the party's position on WWI, a blatantly imperialist endeavor, and many "Leftists" were quick to bash Cuba during the failed Color Revolution to show to libs that they weren't "Authoritarian", this is more accurate than it needs to be.
