Borders

Why have an administrative division line if it has no meaning or implication? Isn't communism, at it's root, democracy? If one federation votes completely differently on one issue than another, those borders are no longer arbitrary or meaningless. Or if one federation votes to remove its association from the global federation over disagreements. How does this not set up a world where you have different factions occupying different areas with different laws?

What in human history makes you believe this is true?

Communism never happen in history, that's the whole point.

…that is the point. Communism has never happened in human history, but not for lack of trying. Communists spent 100 years trying to implement itself globally and failed. That's my whole point. It's not for lack of trying.

I did not know the USA went marxist and tried to implement communism or even socialism, probably because they were busy fucking up every socialist revolution or socialist states on Earth.

Exactly my point again. The USSR tried to implement global communism and got btfo by the USA. It doesn't matter if your car looks the shiniest, or if it's more ecologically friendly and more efficiently engineered - if it doesn't go faster than the other car, it loses. If modern communism cannot compete with modern capitalism on all fronts, there's no point in entertaining the details of these idealistic hypothetical futures.

So why are you talking about Mad Max tribes anyway? Why are you even on a leftist board?

Probably because I fell for the global anarchogommunism meme in my youth and am trying to save other young people years of embarassment and cognitive dissonance.

By what? Saying that capitalism is hegemonic? Everybody here already know that.
You're just another national-conservative who's bitter about "progressive" neoliberalism being the main capitalist ideology nowadays.
Even if you think you're helping nobody here want your help, now please go back to Zig Forums.

I don't personally think some societies are currently compatible. If you place people from a muslim country into a non-muslim country, it could have a negative impact on both parties. Religion in general poisons everything.
I don't think the world in its current state is ready for open boarders.
