No, this is a ridiculous misreading of my comment, and of Marxism in general. When I say "one drop," I mean of private property, not of capitalism itself. Capitalism is an overarching system, it isn't something you define as a quantum element. I already stated that capitalist systems have public ownership, and that that doesn't mean capitalist systems have socialist elements either.

Socialist countries are appropriating capital, yes. Public ownership is the principle aspect of their economies as well. You proceed from a false assumption and base your argument on that, but the premise itself is false. Socialism is a mode of production where public, collectivized ownership is the principle aspect of the economy. Simple as that. It isn't the public sector of a capitalist state, nor is it exclusively a system that is fully collectivized.

Your entire comment is mired in the idealism you accuse me of. I have never once suggested that socialism isn't a mode of production, yet you are here affirming it as something unique, holy even, perfect, ideal, devoid of contradictions, unlike the other modes of production. That's what I meant by it not being unique among modes of production, not that it isn't a mode of production. This concept of socialism being pure when no other mode of production is is the very utopian idealism Marx railed against when correcting Hegel's idealist dialectics. All modes of production contain contradictions, all modes of production contain elements of other modes of production. If you erase dialectics and only look at systems by their purity, you'd find that all modes of production fail to be correctly analyzed, because none are pure.
