In regard to my previous post, On Political Correctness, what I experienced in the neighborhood Facebook groups has a name: “white fragility.” Per the linked interview:
SAB: What causes white fragility to set in?
RD: 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. This is one of the most effective adaptations of racism over time—that we can think of racism as only something that individuals either are or are not “doing.”
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.
