It is important, because it implies Molyneux would take steps to build such a state, when he wouldn't on principle. Molyneux is an anarcho-capitalist: he desires there to be no state at all.

It just happens to be a convenient feature of said anarcho-capitalist society that he would be free to oppress non-whites. You're cherry picking one particular argument he makes without considering his other espoused beliefs.

I think precision is important in this context, because people have a bad habit of using terms like "white supremacist" as generic insults against any right-wing figure. Being imprecise diminishes the force of the arguments against Molyneux, who really has made explicit claims that white people are better than everyone else.

I agree with you. I edited my original comment to clarify a bit.

> who really has made explicit claims that white people are better than everyone else.

Where?
