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.
