The #masses, #socialists, and #women are (incentivized to be) more equal than not, by their #definition and their #biology, respectively (Gustave Le Bon).
Hence, #propaganda, whose point is #mass #formation and #herding, must be more #socialist and eventually become more #feminist than not.
The #national-#socialists and the #cultural #marxists knew and applied that, the latter later and thus to greater extent.
