Judith Butler's feminist agenda was shaped by significant challenges, particularly in relation to gender theory and issues of identity. Encountering both academic opposition and personal reflections on her own experiences, Butler critically examined the social constructs surrounding gender and sexuality. The backlash against her seminal work "Gender Trouble" highlighted the ongoing tensions in feminist discourse, as her ideas challenged traditional notions of binary gender roles. Additionally, Butler's engagement with queer theory emphasized the fluidity of identity, prompting a more inclusive approach within feminism that sought to address intersectionality.
