This article provides a basic psychological conceptualization of racial trauma. It considers how seemingly minor instances of bias or discrimination can lead to posttraumatic reactions, the proportions of which can be hard to understand from the outside. I propose to describe this non-extraordinary event of racially biased treatment as the discriminatory gesture in order to emphasize its fluidity and pervasiveness as an interpersonal event. Being the subject of a discriminatory gesture represents a unique source of trauma, particularly because it derives its destructive power from its occurrence in a wider contemporary context of pervasive racism, white supremacy, and the historical context of slavery.
