Cultural Marxism is a branch of Marxist ideology formulated by the Frankfurt School, which had its origins the early part of the twentieth century. Cultural Marxism comprises much of the foundation of political correctness. It emerged as a response of European Marxist intellectuals disillusioned by the early political failures of conventional economic Marxist ideology.
The central idea of Cultural Marxism is to soften up and prepare Western Civilization for economic Marxism after a gradual, relentless, sustained attack on every institution of Western culture, including schools, literature, art, film, the Judeo-Christian religious tradition, the family, sexual mores, national sovereignty, etc. The attacks are usually framed in Marxist terms as a class struggle between oppressors and oppressed; the members of the latter class allegedly include women, minorities, homosexuals, and adherents of non-Western religions such as Islam. Cultural Marxism has been described as “the cultural branch of globalism.”
