The goal of the Frankfurt school, Antonio Gramsci, Saul Alinski and the like, was to implant the notion in society, that everything must be perfect without question, or that it was entirely corrupt and worthless without question, and therefore must be destroyed. That something could not be good and true, but flawed. Any flaw or defect required the institution or principle be destroyed, and replaced or rebuilt to "perfection".
They presumed, that if they were successful in doing so, the system would collapse (and thus "western culture" which they loathed, would collapse with it), as everyone would understand that things were not perfect, and therefore everything was corrupt and worthless... and thus would remove their support from the system.
They have, in fact, been entirely successful. The dominant motive emotion... no thought is involved... in society today, is what we call the "zero defect" concept, and culture.
Where the radicals failed... and what has kept "the system" running as it is... Is that they did not understand that most people, have an absolute emotional need for stability and confidence in authority and "the system".
Thus, rather than rejecting the false and toxic notion of the zero defect culture, or tearing "the system" and thus western culture and civilization down with it... as the radicals believed and desired would happen; a large number of people simply refuse to acknowledge or admit any defect... and attack anyone who claims defects exist, as if they were attempting to destroy the country, and society.
