Dyson is a sociology professor and a pastor, so this sermon is fully informed by social science. But rather than reaching an audience with scholarly knowledge, Dyson goes straight for the emotional gut punch and succeeds resoundingly. If you're white and you've ever thought to yourself questions like "What about black-on-black violence? Why is the n-word OK for black people to use? What's with the support for O.J. Simpson? Do we really need reparations?", this book is for you. Dyson clearly lays out why continuing outrage isn't enough. Change must be made to happen.
