I get what you're saying about those who are TRYING to help...but in cases where they're actually causing more net harm than benefit, their actions are making the long-term struggle that much more difficult for everyone, on-balance.
DiAngelo is either blithely unaware of this...or she indeed realizes it, but doesn't care because she's too busy cashing in on her persona. Either way, "well-meaning" people who are making the situation worse need to have enough self-awareness to correct their rhetoric/behavior...and I see no such humility from DiAngelo or her ilk.
