Our entire intellectual/cultural class have been turned en masse into the intellectual equivalent of the Manson Family by a simple yet ugly process of Skinner Box cultural conditioning.
First the device/rat trap is the delivery method: Smartphones, constant internet access, and social media have turned out to be the greatest tools of social conditioning and mass-opinion control and formation ever invented, they have created a digital panopticon of docile anxious conformists constantly monitoring each other for social miscues or deviations from orthodoxy, all happy to report each other to the authorities for social credit and virtual virtue points.
Next is the delicious hate pellet they ingest when rewarded by His Majesty, the Algorithm: the Maoist Maniachean moralism of Social Justice, which tricks its user into believing by vomiting out new jargon about "Oppression" and "marginalization" etc they become part of a moral priesthood, which allows them to denounce and destroy every opponent without tarnishing their virtual halos, because (as all the Good People know): nothing exists but Power and Silence is Violence.
It's hard for liberals with 20th-century brains still intact to accept and acknowledge what's happened: an entire generation and all the institutions it controls have been lost to an apocalyptic death cult that have the same morals and ruling strategy as Lady Macbeth.
They will not be coming to their senses anytime soon, if ever, so will have to be opposed and defeated if free thought, speech, and expression are to survive.
