Since someone in comments challenged my assertion that neither the Soviet nor Maoist Chinese states were communist, I thought I would clarify my view on this.

By definition, communism refers to a stateless society in which the citizenry own the components of production, including land, resources, money, and labor in common.  The USSR and “Communist” China could therefore by definition not be communist, since they included a state apparatus.

Though these governments justified themselves as an intermediary step between capitalist and a communist society, I argue that they really existed only as a way to institutionalize the consolidation of wealth in the hands of elites.  This makes them authoritarian and tyrannical, perhaps, but it does not make them communist.

In a sense, the commenter has offered an example in support of my argument that social discourse matters.  Since he grew up on a social environment that classified these governments as communist, he refers to them so, whatever Engels, Marx, or anyone else says.  They were communist only in the sense that he believes they were.
