[In my ratings 2 means quite OK and 3 means good.]
Nobody exposes injustice without quite bludgeoning the reader, an accomplishment for a book-length argument. One quibble: I never felt that the titular category was well-defined. In the end I decided, somewhat circularly, that it means 'people who, when one sees their realities, one thinks deserve better treatment from society than they get.' I found myself reading very quickly and wanting to be finished, only to chastise myself with awareness that reading enjoyment is anything but the point. It's a helpful book that is timely for simultaneously sharpening the focus and broadening the reach of the necessarily simple Black Lives Matter slogan.
