—“Why is neo-progressivism so reliant upon the re-appropriation of Marxist doctrine and Critical Theory?”—
1) Conservatism must speak in historical, moral, allegorical, and religious language because if stated ratio-scientifically it’s reducible to ‘eugenics in everything’, just as all of western civilization has been since the Kurgan invasions. So conservatives do not lie they just do not speak the truth.
2) Neo-Liberalism is just an attempt to turn america into the levant or south america so that an upper managerial caste can form and profit from administration of a vast underclass, just as the cosmopolitans did in eastern Europe before migrating to the states. They cannot say this. And there is no way to speak truthfully. Since they failed at pseudo-rational marxist religion, pseudoscientific economics and social science, and just gave up advocacy and started attacking western civilization at every level (cultural marxism / postmodernism / the frankfurt school).
Democracy creates incentives to lie. Rule of law (constitutionalism) creates incentives to tell the truth. But conservatives don’t tell the truth, and neo-liberals just lie.
Humans are vastly unequal and our evolution has been 5x that of the difference between humans and chimpanzees over the past 30k years alone. These differences are largely visible as differences in rates of maturity, depth of maturity, and sexual dimorphism, and the relative sizes of the lower and upper classes.
This means that conservatism is true but a large domestic empire is impossible. It means that progressivism is false, and that a large domestic empire will produced colored casts very much like india with little or no rotation.
The only solution is to break up the empire and continue the BIG SORT.
