Cultural Marxism conspiracy theory:
The term “Cultural Marxism” refers to a far-right antisemitic conspiracy theory which claims that Western Marxism is the basis of continuing academic and intellectual efforts to subvert Western culture. The conspiracy theory misrepresents the Frankfurt School as being responsible for modern progressive movements, identity politics, and political correctness, claiming there is an ongoing and intentional subversion of Western society via a planned culture war that undermines the Christian values of traditionalist conservatism and seeks to replace them with the culturally liberal values of the 1960s.
But I am sure you knew that, right? An anti-Semitic dog whistle is what it is.
