popularized in a game called Call of Duty

a) CALL (ongoing action) generates DUTY (temporary reaction)

b) OF duty implies as suggested reactions to one another aka temptation for oneself to ignore call of perceivable.

c) consenting as person (singular) to suggestions by others; collectivizes self into people (plural) aka a popularizable populace aka pop-culture (cultivating popolo; people).

why would they do such a thing?

The many (populace) consenting to the suggestions (call of duty) by the few; give the few not only the power of the suggested; but also the opportunity to control whoever makes suggestions.

Mass consent to suggested words over perceivable sound was already given, and so now whoever shapes suggestions out of words is operating within a controlled environment.

Yuri Bezmenov can talk about ideological subversion as much as he likes without endangering those subverting. Why? Because LOGIC; LOGOS (words) is being used by both those who subvert and those who try to straighten up subversion. Those willingly under the spell of words can't read words without keep falling for the spell...they lack discernment between perceivable (sound) and suggested (words) which represents each ones free will of choice (need over want or want over need).

completely controlled

Complete (whole process of dying) controls partials (living)....others suggest "complete control" to tempt partial ones to ignore being within perceivable whole.

originally Jewish

Perceivable sound represents origin of suggested words like "jewish". Ones consent to the latter tempts one to ignore former.

people who founded

Foundation of partials implies whole...not each others suggested funding. If a many ignores this, then a chosen few can utilize mass ignorance as the foundation for mass subversion.

Frankfurt School

Aka FORT (fortis; forticfication) of the FRANK (open; ingenuous; free) aka dominance of balance as the fortification for each ones free will of choice...unless ignored.

How can one be distracted from response-ability (free will of choice)? By suggested SCHOOL, noun (Latin schola; Gr. leisure, vacation from business, lucubration at leisure, a place where leisure is enjoyed).

brainwash

WASH (inception towards death aka flow) generates BRAIN (life aka form). Brain needs to resist wash....others suggest brain to ignore resisting; hence getting washed away as flotsam for pirates out to loot.
