Your instance, Lemmy.today, federates with Hexbear. We don't. Not all criticism of capitalism is in the service of dictatorship.
Anarchists invented the term 'tankie' to describe authoritarian defenders of the USSR in our fight for survival against attack, imprisonment, and assassination by agents of the Bolshevik state. This is an anarchist meme, posted by an anarchist, on a Lemmy instance run by anarchists. You're using the word wrong.
If you see authoritarianism whenever people criticize neoliberal government, the problem is you. Fix your brain rot.
You wouldn't know a tankie if one rolled over you with tracked treads.
The core of the term 'tankie' comes from when the USSR sent tanks into Hungary in 1956 to institute a pro-Warsaw Pact regime change. Western governments are also big fans of sending mechanized infantry to install dictators. If you are an ideological partisan of western 'democracy' you have more in common with tankies than the poster does.
Simultaneously believing "Nazis were bad and actually socialist" and "Nazis were okay because they fought Russia, who were actually fascist" is a pretty big red fascist flag.
