This work presents a philosophical defense of anger at racial injustice. It shows that this type of anger - what author Myisha Cherry calls Lordean rage, honouring Audre Lorde - can inspire us to change the world. For that reason, we should seek to cultivate it, rather than push it down. Crossing the terrain of moral psychology, philosophy, and current affairs, the book shows how anger at racism is an appropriate and even necessary way of valuing others, how anger can motivate those who are outraged to engage in productive action, and how anger strengthens us to become the heroes that we have been waiting for. Beyond laying out the theory behind her case for rage, Cherry shows racially marginalised people and their allies how to better manage and channel anti-racist anger in order to affect lasting, long-awaited change.
