Audre Lorde's works addressed several critical social justice issues, including racism, sexism, and homophobia. As a self-identified Black lesbian feminist, she explored the intersections of these identities, emphasizing the importance of marginalized voices. Through her poetry and essays, she advocated for self-acceptance and recognized the power of difference as a means of social change. Her defining works, such as "Sister Outsider," sought to foster solidarity among oppressed groups, bridging gaps between various social movements and promoting a more inclusive approach to feminism and activism.
