Cultural Marxism conspiracy theory

Cultural Marxism is a far-right antisemitic conspiracy theory that misrepresents Western Marxism (especially the Frankfurt School) as being responsible for modern progressive movements, identity politics, and political correctness. The conspiracy theory posits that there is an ongoing and intentional academic and intellectual effort to subvert Western society via a planned culture war that undermines supposed Christian values of traditionalist conservatism and seeks to replace them with culturally progressive values.
