Critical Theory is the removal of economics from Marxism. That's not me saying so...the creators of Critical Theory stated that up front.
Critical Theory can thus be applied to a number of other movements. But one central component of Critical Theory brought over from Marxism is the proposal of eternal class conflict between Oppressor and Oppressed, which in Critical Theory is not economic class but other classifications such as race and sex.
Thus, in Critical Race Theory, the eternal class conflict is and will _always_ be between whites and non-whites. In this eternal conflict of Critical Theory, there can never be reconciliation, treaty, or compromise between whites and non-whites.
In Radical Feminism, the eternal class conflict is between males and females with males as the oppressors, and there can never be reconciliation, treaty, or compromise between them.
The only acceptable outcome in Critical Theory is vanquishing the Oppressor.
