Scholarship in the area of cross-racial organizing between Latina/o and African Americans has increased substantially over the past ten years. Within that literature, scholars have identified many reasons why cross-racial coalitions both succeed and fail. Among the factors most often cited is the issue of trust. Despite the recognition of the crucial role trust plays in cross-racial organizing, little attention has been paid to what contributes to actually building trust between African Americans and Latina/o. I argue that one factor contributing to the distrust of Latinas among African American women involved in cross-racial organizing in Atlanta is the perceived discrepancy between Latinas’ own asserted identity and the identity assigned to them by African American women organizers. Using data gathered from six years of participant observation and forty interviews conducted with African American women and Latinas organizing in Georgia, I discuss the consequences of identity construction for cross-racial organizing. I find that within cross-racial organizing spaces in Atlanta, perceived racial identities are used by African American women as proxies for determining Latina organizers’ commitment to social justice and, correspondingly, how much individual Latinas can be trusted. Specifically, I find that African American respondents view Latina identity as optional and potentially white. Latina respondents, on the other hand, assert strong identities and contend that their perceived “optional” identities are a function of what Anzaldúa calls a mestiza consciousness or the straddeling of multiple identities. I argue that understanding how these identities are assigned and asserted by Latinas and African American women is a crucial and often-overlooked component to building trust, and by extension, to building sustainable cross-racial coalitions.
