Uh, in no way is "the author" arguing that we should move on from the race conversation. I'm simply saying that the conversation is better led by people who aren't racist.
Standpoint epistemology is all well and good, but applied as it all too often is, it simply reinforces the racist idea that groups of people are monoliths instead of individuals. It suggests, in the case of White Fragility, that because DiAngelo is racist, all white people must be. Or in the case of black people. that our "trauma" with regards to race is all the same or is equally based in fact.
Standpoint epistemology is a nice, fancy way of saying "my opinon". And that's fine. People's opinions should be heard. But when we start mistaking opinion for fact, especially from the most damaged individuals in a group, we're not likely to end up anywhere productive.
