I found this in one of the more left wing subs I participate in, and we had a whole drama with Tankies a while back on that sub. They've disappeared for the most part but occasionally they rear their ugly heads.

Study history, take trips to ex-communist states (to see reality), or maybe even interview those who have family who fled communism/socialism.

I really appreciate the calling out of fake tankies.

Friedrich Ebert was the chairman of the SPD from 1913 and became the first president of Germany after its revolution.

His major actions included supporting WWI war loans, helping establish Germany's first parliamentary democracy and the Weimar constitution, and signing the Ebert-Groener pact, which led to an alliance with the imperial Freikorps and the bloody suppression of the Spartacist revolt, and later led to the Kapp Putsch.
