Which is why it’s a utopian movement.
Nothing could be further from the truth. Marxism-Leninism is fundamentally opposed to utopianism, and idealism in general.
- Friedrich Engels: Socialism: Utopian and Scientific
- V.I. Lenin: “Left-Wing” Communism: An Infantile Disorder
- Mao Tse-tung: Oppose Book Worship
- Georges Politzer: Fundamental Principles of Philosophy » Utopian Socialism
Regardless of what Marx and Lenin declared about their stance with regard to utopianism, communism is utopian in the sense that it doesn’t exist, and can only exist in a world that is fundamentally different than this one.
You’re saying communism can’t exist while not having even a Wikipedia-level understanding of capitalism or communism, so you’ll excuse me if I disregard your opinion.
