There is a low-functioning, parasitic, and culturally alienated group, which has a defect rendering it incapable of reproducing except through artificial means, which they erroneously refer to as “education.” This group is colloquially referred to as “liberal,” though unsurprisingly many of them do not accept the label.
Everybody else falls into a separate group, which goes by many names but is generally called “sane.”
Perfect! Liberalism is a meme that prevents the host from reproducing at a total fertility rate sufficient to maintain the infected population. Infants born to that population (as to any other) are chthonically traditional, but education infects them with liberalism. Education is the only way the liberal meme can survive from one generation to the next. Those infected defect from their natural ethny (routinely rebelling even against their liberal parents), and from all others. This leads to anomie, alienation, isolation, loneliness, and the host of psychopathologies to which liberals are famously prone: depression, anxiety, rage, paranoia, and so forth.
There is a cure for liberalism, but few seem constitutionally capable of completing it: radical metanoia. Resort to a red pill under conditions of extreme cognitive dissonance can start the process, but absent complete repentance it cannot fully take.
