Final answer:
Susan Moller Okin criticizes John Rawls' theory of justice for not specifically addressing gender inequality and for potentially perpetuating it by failing to consider the unique social and familial roles of women.
Step-by-step explanation:
Feminist political philosopher Susan Moller Okin's argument against John Rawls' approach is that it does not adequately address the inequities women face, both in society and within the family unit. While Rawls' theory advocates for principles of justice oriented towards equal rights and fair distribution of resources, Okin suggests that these may perpetuate gender inequality by not explicitly taking into account the different social positions and family roles often held by women. She argues that a truly egalitarian society would need to reconsider these gendered aspects and incorporate them into the principles of justice to properly address the specific injustices women experience.
