I look forward to reading her book when it is published to see how she fleshes out her thoughts 

Others, like the NYT’s Charles Blow, have a different opinion.

This all contributes to whittling away at the reality of racism itself, that it even exists in nearly the proportions which social scientists have documented. This refusal to properly and consistently call racism racism allows the pro-racists and the racism deniers to proclaim nearly unopposed that labeling something or someone racist has simply become a weapon, and that the words themselves have lost meaning by overuse.

In truth, the opposite is true: Racism is actually under-identified and labeled in America.

And, I believe that too many of our white neighbors are choosing to be intentionally blind to the enormous breadth and scope of racism in this country, because to acknowledge it would be to condemn self, family, friends and community. It would be to recognize that much of their existence is privileged, and conversely blackness is oppressed.

Shirley Chisholm, the first African-American woman elected to Congress and the first to seek a major party nomination for president, once put it: “Racism is so universal in this country, so widespread and deep-seated, that it is invisible because it is so normal.”

There is racial bias embedded in nearly every aspect of America life: financial, medical, judicial, political, nutritional, environmental, educational, you name it.

Racism in America is like air — all around us, being constantly inhaled and exhaled, and if you are white, proving very beneficial to your health and survival.

It is precisely for that reason that many white people are incredulous when they see a person of color heaving, gasping for breath, complaining that the air is poisoned.

As  Blow notes, denying racism supports it.
