The nature of liberal society, no, it’s entire foundation, is based on the systems of oppression. In the response to this fact, two reactions have formed: leftist thought, and fascism. Fascism is an embracing of the foundation of oppression, which liberalism chooses to ignore. Leftism is instead the rejection of this foundation.
Many liberals seek to destroy the foundation, but they also seek to keep the structure of liberal society. This is impossible.
