Communism is what happens when Socialists realize that they want complete control over every aspect of human life.

Every totalitarian Communist considered themselves as a Socialist first and foremost.

The central planners of Democratic Socialism tighten their noose when people resist their plans and assert their rights. All Socialism is intended to devolve into Communism, and as a result, Totalitarianism.

The desire to engineer humanity is a sign of a mind warped by megalomania and lust for power.

A "centrally planned economy" by definition discourages and despises participation by the masses. It's a bureaucratic oligarchy.

Thomas More's Utopia was not a recommendation. It was a warning.
