The Frankfurt School of Political Correctness is certainly a big part of what you may be referencing, and the origin of Critical Theory. Some very influential intellectuals who held and expounded upon toxic, anti-tradition and anti-Western values were imported to the US and their work massively promoted.

Here are the 11 Principles they were focused on promoting:

1. The creation of racism offences and hate speech laws.
2. Continual change to create confusion (e,g., in school curricula).
3. Masturbation propaganda in schools, combined with the homosexualization of children and their corruption by exposing them to child porn in the classroom.
4. The systematic undermining of parental and teachers’ authority.
5. Huge immigration to destroy national identity and foment future race wars.
6. The systematic promotion of excessive drinking and recreational drugs.
7. The systematic promotion of sexual deviance in society.
8. An unreliable legal system with bias against the victims of crime.
9. Dependency on state benefits.
10. Control and dumbing down of media. (Six Jewish companies now control 96 percent of the world’s media. LD).
11. Encouraging the breakdown of the family.
12. All all-out attack on Christianity and the emptying of churches.

James Lindsay is an academic who has done the best analysis of Critical Theory and its effects in recent history. He doesn't talk about jews specifically (and is very straight-edge, accessible, and clean cut), but if you look into the personal lives of the critical theorists he discusses: they are almost all jews. Here is a link to one of his talks: https://www.youtube.com/watch?v=rSHL-rSMIro The man has done some great work.
