There are plenty of resources for people who don’t agree with the Robin DiAngelo theory of anti-racism, and not just from people who are white and fragile. Some resources for your book club/HR department/Facebook group/etc:
Kelefa Sanneh in the New Yorker https://www.newyorker.com/magazine/2019/08/19/the-fight-to-redefine-racism
John McWhorter in the Atlantic https://www.theatlantic.com/ideas/archive/2020/07/dehumanizing-condescension-white-fragility/614146/
Carlos Lozada in the Washington Post https://www.washingtonpost.com/outlook/2020/06/18/white-fragility-is-real-white-fragility-is-flawed/
And, of course, these two dumb fucks on Blocked and Reported https://barpodcast.fireside.fm/17i=1000479155349
I also highly recommend this interview with a woman who went through diversity training with DiAngelo herself (great host, btw) https://barpodcast.fireside.fm/bonus2
I also recommend following @kmele, @coldxman, @cvaldary, @GlennLoury, @ZaidJilani, @Yascha_Mounk, and @lwoodhouse for astute commentary on race and anti-racism that you might not get from your Facebook friends.
