You are incorrect, the mass famines of the USSR and CCP were mostly caused by a single conman, named Trofim Lysenko, who was lying about agricultural techniques/results in order to keep his job (taking his bag like a true economic opportunist):

Here's a whole Behind The Bastards podcast about it:

To that point, even the Gulag system whilst being a horrible and targeted system of political persecution, even there the vast majority of victims survived (1 million died in Gulags, 17 million survived). So you're adopting misinformation because you're coopted into Capitalism.
...this is the whole point The Frankfurt School "Cultural Marxists" (people like Marcuse and Adorno) were making. Capitalism is full of such pro-Capitalist propaganda, which Liberals believe without researching it.
Meanwhile almost all Colonialism, since the French Revolution, and the Free Market genocides of the Congo and bengal/india (aka The British East India Company) were done by Liberal minded Economic Capitalists... Intentionally killing WAY MORE PEOPLE with the Liberalism of their day (which turned the other cheek due to racism and sexism).
So I hate to break it to you, but Historical and Cultural versions of your Liberal Philosophies massacred and killed WAY MORE PEOPLE, and did so WAY MORE INTENTIONALLY, than the USSRs and CCPs unwanted famines combined.
But like every Liberal, you have to ignore solid facts of history in order to make your fake claims. You were willingly coopted back then, just like you're being right now. The only question is whether it's intentional or a product of ignorance.
