Because my country, Ukraine, was under communists and it was not good time with all genocides, holodomor, repressions, red terrors and other things

Yes, but none of that is unique to communism, that’s just corrupt government. Anywhere that develops systemic inadequacies and a culture of impunity can instantly become such. That’s just something that is independent of the underlying system of economics. Like many capitalist systems like to point out that bourgeoisie who are after their own interest act as some check on the government who is usually in a power struggle for control. And that power struggle is what ensures no one side wins out.

But there’s nothing technically stopping the rich from becoming the actors of the government and when we as a society excuse profiteering in office, well then there’s no barrier from the rich just becoming the government. Which that’s just the French ancien régime that ultimately lead to the French Revolution.

So it’s NOT specific to just communism. It’s just that’s the most recent and easiest one to point out because of how blatant/brazen that system had become with it’s corruption. Even with all of the “nay-saying” that might happen with United States detractors with their usual hum of “Oh well they’re all corrupt!” Even with how passive some are with it, the corruption is nowhere near the level of being out in the open that was with the USSR. Politicians still weasel their way around because they know that there’s still some bottom level of ensuring checks on that corruption that exist. And we have those checks not because we are a capitalist society.

I think the idea that some economic system promotes some civic purity or prevents some form of government corruption is a bad linking of things that ought not be linked, because a pure capitalist society doesn’t magically inherit some barrier of corruption. That barrier has to be formed independent of the underlying economic system.

I’m not trying to detract from what happened under the USSR but that has way more to do with how power got consolidated post World War I and everything that lead to the toppling of the Russian Monarchy. The system of communism played a role in that consolidation of power, yes, but literally any tool could have been used if you have someone with the mindset of Vladimir Lenin who wanted to rapidly consolidate power during the Bolshevik revolution. I mean look at the current Myanmar Civil War and some of the ideas of General Min Aung Hlaing, no need for implementation of communist ideology there, he just wants to be in power, doesn’t believe that the current transfer of power is legitimate, and is willing to get a lot of people killed in proving that point.

I think given the current situation in the United States, the belief that you NEED communism to have totalitarianism is a dangerous linking of things that can actually happen independent of each other. You just need someone to wear down government legitimacy enough to start a civil war, that’s all you need. Everything else is just tools at your disposal to get that goal done.

So you have to understand the nuance here I’m trying level. I’m not saying it WASN’T COMMUNISM, what I’m saying is that it can be communism, but ultimately you just need someone who wants to consolidate power rapidly and exists in a society that will forgive abuses of power enough, sometimes that’s done by de-legitimizing the current system enough. That’s it, that’s all that’s required. Communism can play a role in that somewhere, but it doesn’t have to.
