I'm skeptical about Robin Diangelo, I read her book a few months ago, and it only seems to be an advertisement for her services as an anti-racist instructor. Her entire argument frames race relations within the context of the workplace which is problematic because her approach is coercive, not educational. It's more a guide on "how not to get fired for being racist" than anything. There are much better books for foundational education about race.
Even within her book she claims that no amount of training will solve the issue, it seems that "White Fragility" is just another way for White people to tamp down the anxiety of race relations in the United States, rather than take any meaningful action towards changing it.
If your goal is to truly understand the Black american experience, it's best to start with actual Black authors. The House That Race Built by Wahneema Lubiano is a great set of essays about race and class structures.
