Feminism has strong ties with Marxism. Modern feminism is basically dominated by Marxist ideology and Marxist critical theories.
1st wave feminism, the right for women to vote and own property was the only true feminism.
2nd wave was started in part by a Marxist named Simone de Beauvior, who was the lover of one of the biggest Marxists of all, Jean-Paul Sartre. Her Book "The Second Sex" (1949) is where "What is a woman" cane from. This is where the idea women can do what men do came from. Simone and Jean-Paul were friends with Mao in China, and influenced the Chinese idea read men and women equal, hence destroying the traditional rules ud men and women in China during their Marxist Not-So-Great Cultural Revolution.
3rd wave feminism said is OK for women to sleep around and be sexual objects and toys for men. They claim they are "liberating" women from the shoal oppression of men.
4th wave feminism, also know as Queer Marxism, or LGBTOEDO+ claims men are women and women are men, and that there are a billion+ genders.
