In what ways does feminism oppose the traditional gender consciousness?

There are many feminist theories, but in the final analysis, it is one sentence: to achieve equality between men and women in all mankind. All feminist theories have a basic premise, that is, women are the oppressed and discriminated class in the world. Beauvoir, a famous French existentialist writer, one of the founders of feminist movement and Jean-Paul Sartre's lifelong companion, called it "the second sex". Women's secondary sexual characteristics are so common and persistent. In such a cross-historical and cross-cultural ubiquitous social structure, women are in an unequal position with men in political, economic, cultural, ideological, cognitive, conceptual and ethical fields, and even in private fields such as family.
