It was the best way I could describe them when I was working on studying communism.

I would say cultural marxism is the parent ideology, equivalent in purpose and goal to traditional marxism.

The sub-ideologies as I identified them were those such as feminism, critical race theory, gender ideology, etc that are used to tear down the culture and push demoralization. In my opinion they are too encompassing to be movements or theories, that’s why I settled on the term sub-ideologies.
