I agree that talking about partisan labels is unlikely to lead to useful analysis (although the game-theoretic and principal-agent issues in the recent budget stand-off in the US are interesting).
But I think noting the contours of ideological movements (like socialism, feminism, or Moldbuggery) is valuable. The sentence:
That point by Moldbug is interesting, but it is not unique to his philosophy. Economists, feminists, psychologists, socialists, and dwarves all assert essentially identical points.
Just as useful:
For consistency, socialists must also assert position Y, which most non-socialists reject.
Some of our disagreement might be that in the US, socialist (or green or monarchist) is not a partisan label because there is no serious political party that asserts those views. Europe has more diverse active political movements.
As Multiheaded added, "Personal is Political" stuff like gender relations, etc also may belong here.
