Nonsense. I'm saying that people live in the real world with real contexts, not in Context-Free-Abstraction-Land.

Real contexts, where abstract concepts have been concrete realities, put natural and rational limits on the ability to treat those concepts as abstract ideas to be debated solely on their hypothesized merits rather than their hard realities. There is a very rational difference between arguing in favor of communism on an American college campus, where communism is a lovely abstract ideal, and arguing in favor of it in Romania or Ukraine where communism was a brutal reality.

Moldbug is an American, being read by Americans, writing about his support for the institution of slavery, and explicitly saying that some races are genetically better suited for slavery than others. It is far more rational to treat that as racist than to bend over backwards and pretend that it is not in the name of free debate.
