The Soviet Union did not kill all those nazis out of the goodness of their hearts, but rather because they were in active warfare with Nazi Germany and thus needed to kill a large number of nazis to win the war. Throughout history, authoritarian “socialists” have backstabbed, betrayed, and otherwise killed anarchists and democratic socialists. I absolutely do not trust tankies to fight against fascism in the United States or Europe in any effective manner. Russia and China are not friendly countries to queer rights, though being gay is legal in both countries they do not have any anti-discrimination laws that apply to queer people and the reason there are fewer hate crimes is simply because they don’t count them. Russia and China are also not socialist, Russia is an explicitly oligarchical capitalist Presidential republic and China has a mixed economy that heavily relies on markets with private owners. This is honestly a good part of the reason I’m suspicious of tankies, the United States sucks but that doesn’t mean that every nation that opposes the United States is automatically good.
