Liberals when talking about human rights: :) Liberals when talking about the enforcement of human rights: :(

Tankies ≠ leftists ≠ liberals

Plenty of leftists want human rights and even know we'll need a revolution to get them, but the USSR and CCP were not ever communist, they were authoritarian oligarchies disguised as communism. The same way the US is not a democracy or a republic, it's an authoritarian oligarchy disguised as one.
