White Fragility, has been on the New York Times best-seller list for over two years, much of that time ranked number one. The book is assigned frequently in college courses, and DiAngelo is in great demand as a “diversity” consultant to help corporations, universities, government agencies, and other institutions purge themselves of their white privilege. DiAngelo’s core message is that white Americans need to acknowledge their unconscious racial biases which make them, unwittingly in most cases, complicit in what she deems the U.S. racial caste system. In an error that aligns perfectly with her ideology, DiAngelo gets this episode of U.S. history all wrong.
