Fitness YouTuber drops some TRP knowledge. Why are we taught the opposite in society?

Here was (a sloppy) part of an argument that I had for biological/sociological indicators healthy humans engage in monogamous relationships

The other part to this argument (why anyone would be motivated to lie about this and distort it) requires an understanding of "Critical Theory", a social engineering theory that attacks and deconstructs social identities and relationships

Neomarxism replaced old Bolshevism, and brought "social revolution" to SLOWLY replace the "outdated" class struggle concept. "Revolutionaries" like Herbert Marcuse, Wilhelm Reich, and Paul Goodman replaced Marx, Trotsky and Lenin as required revolutionary reading.

Herbert Marcuse wiki does a decent overview:

Herbert Marcuse (/mɑːrˈkuːzə/; German: [maɐ̯ˈkuːzə]; 1898–1979) was a German-American philosopher, sociologist, and political theorist, associated with the Frankfurt School of Critical Theory. Born in Berlin, Marcuse studied at the universities of Berlin and then at Freiburg, where he received his PhD.[3] He was a prominent figure in the Frankfurt-based Institute for Social Research – what later became known as the Frankfurt School.

His best known works are Eros and Civilization (1955) and One-Dimensional Man (1964). His Marxist scholarship inspired many radical intellectuals and political activists in the 1960s and 1970s, both in the United States and internationally. He viewed the integration of Eros and Logos to be the liberation of society.

In the post-war period, Marcuse rejected the theory of class struggle and the Marxist concern with labor, instead claiming, according to Leszek Kołakowski, that since "all questions of material existence have been solved, moral commands and prohibitions are no longer relevant." He regarded the realization of man's erotic nature as the true liberation of humanity, which inspired the utopias of Jerry Rubin and others.

Antifa neomarxist groups advocate "early managed sexualization of children" to literally prevent fascism, while citing neomarxist Wilhelm Reich

By drawing on the work of Wilhem Reich, who examined the idea of fascism as a symptom of sexual repression, we are taking the 'Reicheann approach' by advocating for the early managed sexualisation of children so as to prevent the formation of any earlier fascist traits.

"Critical Theory" establishment shills literally view healthy humans needing to be biologically experimented on and "reconstructed" neurologically like this piece considers in 2015 about "threat processing parts of the brain":

Disabling parts of the brain with magnets can weaken faith in God and change attitudes to immigrants, study finds

By shutting down the threat-processing centre of the brain, scientists weakened people's faith in God and made them less prejudiced

And what this 2017 study "investigates" modification of neurological hormones for political goals (pro "refugees" bs):

Oxytocin-enforced norm compliance reduces xenophobic outgroup rejection.

Never before have individuals had to adapt to social environments defined by such magnitudes of ethnic diversity and cultural differentiation. However, neurobiological evidence informing about strategies to reduce xenophobic sentiment and foster altruistic cooperation with outsiders is scarce. In a series of experiments settled in the context of the current refugee crisis, we tested the propensity of 183 Caucasian participants to make donations to people in need, half of whom were refugees (outgroup) and half of whom were natives (ingroup). Participants scoring low on xenophobic attitudes exhibited an altruistic preference for the outgroup, which further increased after nasal delivery of the neuropeptide oxytocin. In contrast, participants with higher levels of xenophobia generally failed to exhibit enhanced altruism toward the outgroup. This tendency was only countered by pairing oxytocin with peer-derived altruistic norms, resulting in a 74% increase in refugee-directed donations. Collectively, these findings reveal the underlying sociobiological conditions associated with outgroup-directed altruism by showing that charitable social cues co-occurring with enhanced activity of the oxytocin system reduce the effects of xenophobia by facilitating prosocial behavior toward refugees.

And people wonder why so many people complain about "social engineering" and "social justice going way too far".
