For white people, their identities rest on the idea of racism as about good or bad people, about moral or immoral singular acts, and if we’re good, moral people we can’t be racist—we don’t engage in those acts. . . . In large part, white fragility—the defensiveness, the fear of conflict—is rooted in this good/bad binary. If you call someone out, they think to themselves, “What you just said was that I am a bad person, and that is intolerable to me.” It’s a deep challenge to the core of our identity as good, moral people.
