Co-optation is the process by which a group or movement is assimilated into a larger entity, often resulting in the alteration or dilution of its original goals and values. This can occur when dominant powers or organizations adopt elements of a marginalized group's agenda to neutralize dissent, thereby maintaining their control while appearing to address social concerns. In the context of transnational feminist movements, co-optation can manifest as mainstream feminism or international organizations integrating feminist issues into their frameworks without fully embracing the intersectional and diverse perspectives of grassroots movements.
