Growing up white in America in the second half of the 20th century, I assimilated a negative view of the Nation of Islam that was not dissipated by reading Manning Marable's biography of Malcolm X. With Malcolm's face on the cover of this book, I thought it would be more about him than it is. However, it does provide a detailed and thought-provoking history of the activism of the NOI against police brutality and mistreatment of prisoners, well before the most recent wave of similar activism in the last 15 years. It's organized topically rather than chronologically. Even within the chapters, I sometimes found the chronology confusing, as events are brought up when relevant even if it ends up causing the dates to jump around a bit.
Felber is not here to defend the NOI, and he takes as a given that they were an organization nowhere near as violent or negative as their general reputation. Since he does not seriously undertake to persuade you of that viewpoint, you have to take it on faith and absorb the rest of the information he gives. Certainly we know now, if we didn't know then, that any organization that seeks to stand up for people of color and put them first always gets accused of wanting to harm white people, so it's highly likely the worst of their reputation was undeserved. They were definitely victims of racist policing and violations of civil rights. How their members conducted themselves in prison and how they went about asserting their civil rights were ahead of their times.
Felber asserts, without explaining, that the NOI was completely consonant with mainstream Islam, and again it's not his brief here to take that argument on. I know only a little about Islam, and I remember from the Malcolm biography that he did return from Mecca with ideas about the differences between the two. It is true that Malcolm said, There aren't "Black Muslims," there are Muslims and we are black. That's also a topic for other sources.
There have been black feminist critiques of the NOI (I cannot remember where; was there something on this in the Black Woman's History of the US? Sorry!) for the way they subordinated women. In a few places, Felber inserts a few pages disputing or "contextualizing" the assertion that the NOI perpetuated oppression of women, but they read as though they were added after the book was done, in order to say he doesn't avoid the issue, and seem disconnected from the rest of the narrative. His argument seems to boil down to: Black women were not entitled to the same protections white women were in US society, so for black men to speak for them and guard them and so on was an assertion of their value that they usually didn't receive. Maybe; I'm not sold, but I'm white so that may not matter. I'd love to read reviews of this book by black women.
On the whole, worth reading and I'm glad I read it. Black Lives Matter is an assertion that has been necessary long before it was formulated in those words.
