But the disturbing challenge of your book is your rejection of the American dream. My ancestors chose to come here. For them, America was the antidote to the crushing restrictiveness of European life, to the pogroms. For them, the American dream was an uplifting spiritual creed that offered dignity, the chance to rise.

Your ancestors came in chains. In your book the dream of the comfortable suburban life is a “fairy tale.” For you, slavery is the original American sin, from which there is no redemption. America is Egypt without the possibility of the Exodus. African-American men are caught in a crushing logic, determined by the past, from which there is no escape.

You write to your son, “Here is what I would like for you to know: In America, it is traditional to destroy the black body — it is heritage.” The innocent world of the dream is actually built on the broken bodies of those kept down below.

If there were no black bodies to oppress, the affluent Dreamers “would have to determine how to build their suburbs on something other than human bones, how to angle their jails toward something other than a human stockyard, how to erect a democracy independent of cannibalism.”

Your definition of “white” is complicated. But you write “ ‘White America’ is a syndicate arrayed to protect its exclusive power to dominate and control our bodies. Sometimes this power is direct (lynching), and sometimes it is insidious (redlining).” In what is bound to be the most quoted passage from the book, you write that you watched the smoldering towers of 9/11 with a cold heart. At the time you felt the police and firefighters who died “were menaces of nature; they were the fire, the comet, the storm, which could — with no justification — shatter my body.”
