Feminist theories aim to understand the oppression and subordination of women. Liberal feminism argues that laws treating women as lesser than men arose from ignorance and should be reformed to expand women's rights and opportunities. Marxist feminism locates women's oppression in their treatment as property alongside private property. Socialist feminism sees capitalism and patriarchy both benefiting from unpaid domestic labor. Radical feminism sees men as oppressing women through control over reproduction and child-rearing, calling for women's separation from men. Contemporary debates discuss intersectionality and challenging the gender binary. Feminism aims to achieve a society with equal opportunities between men and women.
