The prc and ussr both had famines, yeah. One of the greatest tragedies of the sino soviet split is the lack of cooperation during the chinese one.

I don’t know what people told you, but there absolutely was a ton of misinformation about the soviet famine that got revealed once 1992 rolled around and the archives opened up. Turned out they had some terrible fuckups and bad luck but there wasn’t any deliberate starvation.

Communists argue about this stuff all the time, we just recognize people trying to understand conflicting information versus people trying to have a big fight or a debate. Part of the reason you get so much flak is because someone interested in learning how to understand conflicting information will gladly read a two hundred page analysis of a four hundred page historical text and discuss it openly while a person looking for a fight will call names and act like bringing up the famines is some gotcha that unmasks the internet communist for the scooby doo villian they are.

The Ukranian Holodomor was the direct result of Stalin’s (and/or his people) actions. When your country has dictatorship, the economic system is kind of doesn’t matter, everything happens not because of the economic system but because of the will of the dictator.
The main pillar of both socialism and communism is workers collectively owning the means of production, this is directly contradicts to the autocracy that was USSR.
If you think that China had famine because of communism, you should think that North Korea has famines because of democracy, because they call themselves Democratic Republic.
