Abstract
In this paper I develop a systemic discrimination approach to defining a narrowly construed category of ‘hate speech’, as speech that harms to a sufficient degree to warrant government regulation. This is important due to the lack of definitional clarity, and the extraordinarily wide usage, of the term. This article extends current literature on how hate speech can harm by identifying under what circumstances speakers have the capacity to harm, and under what circumstances targets are vulnerable to harm. It also shows how the capacity to harm can be mobile and involve the construction of new targets. Finally, it bridges the gap between conceptual understandings of hate speech and policy designed to regulate it.
