Taking the Measure of Microaggression: How to Put Boundaries on a Nebulous Concept

How can we tell whether an incident counts as a microaggression? How do we draw the boundary between microaggressions and weightier forms of oppression, such as hate crimes? I address these questions by exploring the ontology and epistemology of microaggression, in particular the constitutive relationship between microaggression and systemic social oppression. I argue that we ought to define microaggression in terms of the ambiguous experience that its victims undergo, focusing attention on their perspectives while providing criteria for distinguishing microaggression.
