With respect to the last question: one can live in a proverbial forest yet not believe in forests and even mock those who speak of forests.
In the same way those whose way of thinking is most polluted by cultural Marxism are often least able to recognize it, it is like berating to them, and the “Frankfurt School” is just something out of the past that some will attest went no where (even though it is everywhere behind and informing their views).
Bingo!
