In the summer of 2018, a celebrity diversity consultant published a book that would soon take the nation by storm. White Fragility: Why It's So Hard for White People to Talk About Racism -- a work equal parts racial theory and manners guide for white progressives navigating multiracial environments -- was released to instant fanfare, immediately landing and sticking a spot on The New York Times bestseller list. Robin DiAngelo's book compounded her fame, winning her innumerable high-profile speaking engagements and workshop appearances at up to $15,000 a showing. And after protests and riots swept the nation following the death of George Floyd in Minneapolis in 2020, she became a kind of court philosopher for the American corporate and political class, offering trainings on racial etiquette to clients as diverse as Levi Strauss & Co., The Bill and Melinda Gates Foundation, Amazon, and the City of Oakland, California.
