My IQ is not 300, but it's sufficient to understand reality:

- Union of Soviet Socialist Republics: operated under the Communist Party's centralized control, with state ownership of production, suppression of dissent, and looked more like communist authoritarianism than democratic socialism.

- CCP, Cuba, North Korea: they call themselves socialists while being led by communist parties.

- Democratic socialism like Sweden, Norway, Denmark: very different from the above.

Well, socialism also includes the National Socialists of various nations ... perhaps we should clarify our terms rather than using an ambiguous word?
