Marxism (as defined in Marx and Engel's "The Communist Manifesto", 1848 - which was based on the work of Weishaupt) has been replaced with Cultural Marxism, which is subset of Critical Theory (remember, Obama taught Critical Race Theory while a lecturer at Univ of Chicago.)
Herbert Marcuse in 1965 wrote "Represive Tolerance." Here is a sample:
The small and powerless minorities which struggle against the force conciousness and its beneficiaries must be helped. Their continued existence is more important than the preservation of abused rights and liberties which grant constitutional powers to those who oppresed these minorities.
Social justice, neoprogressivism, feminism and post-colonialism, to name but a few, are all momvements born out of Critical Theory and thus come under the umbrella of Cultural Marxism. Be its agenda sexual orientation, family, race, culture or religion, every aspect of a persons identity should be questioned, every norm or standard of a society challenged and ideally altered in order to benefit supposedly oppresed groups."
Classical Marxism saw class conflict between the bougiosie and the proletariet, the haves and the have nots. Cultural Marxism sees that conflict between the oppersers and the opperessed. Those with priveledge and those without it. The working class has been replaced by minorities. The majority group is labeled the oppressors and the minority group the oppressed. Heterosexuals are oppressive, one-gender people are oppressive, whites are oppressive (especially white men), Christians are oppressive. Those that don't fit into these groups are thus considered oppressed.
I went what is considered the most conservative seminary in the US in a Southern state and I had a big problem in theology courses when liberation theology and black liberation theology specifically were both included and taught not from a viewpoint of heresy but as legitimate orthodox forms of understanding. It was obvious that this was the case due to wanting acknowledge what different groups have added and brought to the table so to speak. However when these theologies are totally out of bounds and heterodox they should have been grouped as heresies and taught in that way. Liberation theology and it’s variants are like a cancer and they were subtly or passively condoned as a form of celebrating diversity; affirmative action for theology. I pointed this out to the professor during a large class and was met with silence. Given this was ten years ago. I was always shocked that a significant amount of both professors and students were likely sympathetic if not openly on the left and people were completely enamored with both green religion and all things international/globalist/ united nations to a fault and many had trouble when asked if they believed in borders and sovereignty for the USA. I’m sure it is only worse now.
