Step One: Create Divisions Among the People
Some short time before his death, Andrew Breitbart was introduced to these videos, explaining "Cultural Marxism," and he spread them around (including to me).
If you don't have time for the videos the short version is this: Although Marxism predicted that capitalist nations would naturally and inevitably undergo communist revolutions, Marx was wrong about this (and much else). It became clear to many Marxists that actually only the sickliest countries were ripe for Marxism; the rich and free countries of the West were largely immunized against the Communist virus due to the success of capitalism there.
Thus the Frankfurt School created a "New Marxism," a Marxism based not on stoking economic divisions in the country but on stoking cultural divisions. The goal was still the same -- undermine the state to such an extent that a revolution was inevitable -- but now the method turned to ginning up hatred and envy between different cultural cohorts along gender and racial lines.
Most Marxist schools incorporate the word "critical" -- Critical Gender Studies, Critical Race Theory. It's always important to remember what Marx meant by "critique" -- a denunciation intended to bring about the war of all against all and thus his glorious, bloody revolution.
War on the German state of affairs!? By all means! They are below the level of history, they are beneath any criticism, but they are still an object of criticism like the criminal who is below the level of humanity but still an object for the executioner. In the struggle against that state of affairs, criticism is no passion of the head, it is the head of passion. It is not a lancet, it is a weapon. Its object is its enemy, which it wants not to refute but to exterminate. For the spirit of that state of affairs is refuted. In itself, it is no object worthy of thought, it is an existence which is as despicable as it is despised. Criticism does not need to make things clear to itself as regards this object, for it has already settled accounts with it. It no longer assumes the quality of an end-in-itself, but only of a means. Its essential pathos is indignation, its essential work is denunciation.
From Marx's introduction to a Hegel work.
This all sounds very familiar to me.
