In 2010, the Arizona State Legislature drew national attention to issues of ethnicity, pedagogy, and censorship in public schools by passing House Bill 2281. As interpreted by Arizona officials, this law made the curriculum of the Mexican American Studies Department in Tucson public schools illegal. The ongoing conflict between supporters and opponents of the Department in public discourse—and in state and federal courts—raises important questions about the ways that majority and minority cultures interact in United States educational institutions. This Note uses Arizona’s ethnic studies ban to suggest that Derrick Bell’s interest-convergence thesis and Lani Guinier’s related theory of interest-divergence continue to be useful tools in assessing the dynamics between powerful and marginalized groups. The Note sets the facts of the ethnic studies controversy against recent criticism of Professor Bell’s work and, in doing so, rebuts the assertion that the interest-convergence thesis has become less relevant to understanding contemporary intergroup conflict in the United States.
