It’s known as Critical Theory.

It is one of the tools being used by the Cultural Marxists to erode the foundations of Western civilization, in particular the American interpretation of it.
All other countries have “sinned” as much or even worse than the U.S., but their misdeeds are not proclaimed as loudly. That’s because the Cultural Marxists have already achieved much of their “long march through the institutions” there. Here, they are encountering resistance that they must double their efforts on.
By the way, one of the other tools they are using is Polymorphous Perversity.
This is what you’re seeing with the “non-binary gender” and various paraphilia movements.
That’s all correct.
And in this regard, the alliance with islam begins to make sense and I’m sure some on the left have figured out that it is the religio/politico system that works best for them to keep the masses in place. It’s very easy to “convert” to, and the five pillars are kept pretty easily by the elite....who can continue to be part of the elite and rub shoulders with the islamic elite (lilke the Saudi royal family) and enjoy the lifestiles of the elites, ruling over the slave cast who must now submit. Just so long as they keep the clerics in line, they are good. And plenty of same sex harams for the perverted. So for the elites, life under (above) islam is just dandy.
