Thank you for leading with a positive comment about Robin DiAngelo's work. I've been mystified by the animus against her. Her lectures on the topic of white fragility which I viewed on YouTube were eye-openers for me. She has named an important concept, given it context, and as a white scholar who has obviously spent most of her professional life seeking to understand the dynamics of anti-Black racism is uniquely positioned to speak to whites on this concept and to deal with the inevitable resistance. And, as you point out, proof of concept is everywhere.
