The societal function of equalism is for upper-class white people to browbeat lower-class white people, because if we’re biologically and materially interchangeable then being poor means you must be a sinful person who deserves to be poor. An illuminated soul would have risen above its material circumstances, like any proper melonhead. The blank slate thing is a nice little trick, if you think about it.
Thus, peacocks preaching equalism in the pulpit is yet another case of the general principle: “Intra-species conflict stems from each phenotype unconsciously trying to alter the environment to favor their respective reproductive strategies.” It’s sexual competition via domination. Thank God the holocene is over because as long as the temperature stays up the global slave plantation will expand its holdings.
