Radical feminism sees patriarchy as a system of male power that oppresses women through social, political, and family structures. Early radical feminism advocated for androgyny and unisex roles, but this view was rejected in favor of acknowledging inherent differences between men and women and the need for feminist struggle and separatism. Radical feminists have debated whether women's oppression stems from their biology or men's biology, and more recently argue that gender itself is a social construct. The movement focuses on women's experiences and aims to understand and end the fundamental oppression of women by patriarchy.
