Cultural Marxism is a derivative of classical Marxism.
Marx proposed that the world revolved around capitalism and there was a power flow resulting from that in which those who had capital oppressed those who did not. His idea was that the workers who were being oppressed would rise up against the bosses and the Communist revolution would occur.
Unfortunately for Marx’s theory, that is not what happened.
Then as time passed, some conceived that the oppressors and the oppressed were oriented on lines other than capital and labor, hence the difficulties between whites (oppressors) and blacks and other minority groups (oppressed); between men and women, between non-transgender and transgender, between heterosexuals and homosexuals, and so on.
As a result, we now have a lot of what is going on today.
Each, classical Marxism and cultural Marxism, relies on the idea of an inherently oppressive quality in one group which absolutely will lead to revolution on the part of the powerless oppressed.
Since this is an actual thing, I am afraid you will have to get used to it. I sympathize.
