As fellow-Harris-supporter Curtis Yarvin reminds us, right-wing authoritarianism looks like a dictator with a cult of personality eroding norms and centralizing power; left-wing . . . badness . . . looks like a semi-decentralized convergence of cultural elites into a stifling monoculture bent on increasing its own power by forcing all government and private actions to go through a gauntlet of priest-bureaucrats drawn from the cultural-elite-class.
Although the exact process is different, both right-wing authoritarianism and left-wing monoculture end in the same place: government control over everything, unfreedom of thought, retribution against dissenters, and the gradual siphoning of all productive activity to serve a parasitic ruling clique.
