Part of the problem is capitalist regimes keep sending assassins to murder leaders of communist movements, such as FBI killing the Black Panther leaders.
Law enforcement in the US is harassing mutual aid organizations. Maybe they're afraid we'll repair the park fences and deny some business a choice government contract?
While you're not wrong, it's important to retain a global perspective. There are "communist" leaders that were total pieces of shit and while they did have help, that help wasn't always capitalist. Stalin is an example here.
And then there's pieces of shit who were supported by external forces, but not by capitalist regimes seeking to undermine them. I'm not 100% confident in this history, and there's no way I'm going to spell his name right, but, the Romanian piece if shit, Caucescu (???) came to power riding a wave of support from the Nazis. Hitler didn't do it to destabilize Romania, but because he was like, "there's some good old fashioned fascist genociders down there, let's give them more guns." And those fascist genociders were technically communists.
What I'm getting at is that the enemies of a worker-ruled communist state are many, and many of those enemies are within their own systems. Communism, like every other system, suffers from the fact that there are humans involved. Just because a communism exists doesn't mean it's going to be utopia.
But that also doesn't mean that communism can't be good, or at least better.
As a note, fascism is a tool of industrialist plutocrats to extend the life of their power as worker class quality of life deteriorates. While Hoover was in power during the Great Depression, US industrialists were looking to Hitler and Mussolini while laborers were looking to the Soviet Union.
As per the Christian nationalist movement / transnational white power movement in the US, our dependence on capitalism has driven us to the verge of civil war, and a push by the Republican party to single-party autocracy and purges of undesirable demographics, including the impoverished and homeless.
I can't speak to Nicolae and Elena Ceaușescu except to say autocracy always tends to go badly, with power consolidated until abuse and corruption is inevitable.
The whole idea behind communism is to imagine what a functional public serving state would look like, and then how to get there from here. Marx speculates on steps that might work to get to a starting point, but much like the framers of the Constitution of the United States, he didn't know everything and couldn't predict how it all plays out in given circumstances.
(US constitutional framers never did democracy before. They favored landowners. They assumed common homesteaders would be driven to understand and vote for their own best interests. And they got broadsided by the industrial revolution. Also, FPTP elections and two-party systems suck.)
We know civil wars tend to lead to serial dictatorships and foreign influencers looking to exploit economic vulnerability. We also grassroots mutual aid movements take generations and are prone to disruption by time and circumstances, particularly raiders and police forces. So we're still trying to chart the geography between here and utopia.
Especially people who never lived in a communist state
That’s a rather impossible requirement, considering that all “communist states” to date have been oligarchic autocracies that were just as much about communism as they were democratic.
Real communism is market ownership by the people, and not some elite cabal of politicians or capitalists. And a top-down planned economy is pretty much anti-communism, as it violates the very fundamentals of communism as being worker-driven.
I don't spend a lot of time promoting communism, but I do talk a lot of shit about capitalism - I've lived in it. Of course when I criticise capitalism people accuse me of promoting communism and having never lived in it.
I think you should read Marx. State planning is definitely in line with Communism, the state is of the Workers and not a separate entity in Socialism and Communism.
Considering how America is moving towards that same state, with it’s Republicans?
No, I don’t think it’s a coincidence. Oligarchic autocracies can occur under any circumstances where a power-hungry elite manage to wrest control by using the masses as “useful idiots”. The Conservative leadership, in general, have learned this trick very well.
