Imagine a professor of physics preaching flat earth, or a chemist preaching alchemy.
The STEM departments, to defend their reputation, would kick these kooks out on their Obamaholes.
However since the lib”arts” departments no longer have standards and very little reputation, they bend to the low-T idiocy of their low IQ “professors”.
In this analogy, the "professors" of this doctrine see themselves not as retro, but as ultra. They are going BEYOND the conventional logic. Unfortunately, the conventional logic includes logic itself, and so, they have entered the TWILIGHT ZONE.
PC was institutionalized in America decades ago. These fringe studies/professors have become mainstream as the bureaucracy of PC has grown in its malignancy.
