An umbrella term for identity politics, affirmative action, feminism, radical LGBT activism, Islam apologetics , white privilege, political correctness... Basically the SJW ideology.What all these things have in common is the fight of the "oppressed" groups against the "oppressor", the white man.Leftists call it the regressive left , because there's nothing liberal about affirmative action (since it violates equality of opportunity), or about silencing your opponents' free speech by labeling it as hate speech.But the point of calling it Cultural Marxism is to recognize that this is fundamentally a Marxist ideology. Marxism is the fight of the oppressed, the workers, against the oppressors, the business owners. Similarly, Cultural Marxism is the fight of the oppressed, the non-whites/women/Muslims/transgenders/etc, against the oppressor , the white man. Both are also international movements.The Frankfurt School (e.g Herbert Marcuse), were Marxists who tried to translate Marxism to the Western world, and are at the root of this ideology.Another way to see the link with Marxism is to understand that affirmative action is all about forcing equality of outcome, as opposed to having equality of opportunity. Similarly, Marxism is based on equality of outcome, since in a communist society everyone would have the same salary no matter what their job or performance is.Marxism is about the "class struggle", Cultural Marxism is about the "struggle of minorities".
