Definition of Cultural Marxism: (not mine, one of the first which came up after a google search, wiki definition too complex)
Cultural Marxism: An offshoot of Marxism that gave birth to political correctness, multiculturalism and “anti-racism.” Unlike traditional Marxism that focuses on economics, Cultural Marxism focuses on culture and maintains that all human behavior is a result of culture (not heredity / race) and thus malleable. Cultural Marxists absurdly deny the biological reality of gender and race and argue that gender and race are “social constructs”. Nonetheless, Cultural Marxists support the race-based identity politics of non-whites. Cultural Marxists typically support race-based affirmative action, the proposition state (as opposed to a nation rooted in common ancestry), elevating non-Western religions above Western religions, speech codes and censorship, multiculturalism, diversity training, anti-Western education curricula, maladaptive sexual norms and anti-male feminism, the dispossession of white people, and mass Third World immigration into Western countries. Cultural Marxists have promoted idea that white people, instead of birthing white babies, should interracially marry or adopt non-white children. Samuel P. Huntington maintained that Cultural Marxism is an anti-white ideology. Critics of Cultural Marxism have maintained that Cultural Marxists intend to commit genocide against white people through mass non-white immigration, assimilation, transracial adoption and miscegenation.
