This seminar examines the development, articulation, and application of "Intersectionality" as both a theoretical frame and a discursive practice in law, human rights, and social justice advocacy. Emerging as a theory to articulate the multiple axis of discrimination encountered by women of color in employment, the family, and elsewhere, Intersectionality has found broader application in efforts to move beyond single-issue and identity-based approaches to societal marginalization. Taking note of the 20th year anniversary of the intersectional framework, the seminar features feminist and critical race scholars, social justice practitioners, and others who will engage, critique, and expand the intersectional prism through exploring its relationship to their own work. Key questions explored include the legal erasure of intersectional discrimination; the circulation of intersectionality in human rights and international discourses; the contested interface between intersectional and anti-essentialist critiques of identity politics; the utility of intersectionality as a prism for understanding coalition failures (i.e. Proposition 8; immigration reform; affirmative action); and the role of intersectionality as a conceptual building block for cross-movement building strategies.
