If humans simply cannot help their tribal instincts, then a truly multicultural democracy has a big challenge ahead of it. The emotions triggered are so primal, that conflict, rather than any form of common ground, can spiral into a grinding cold civil war. And you can’t legislate or educate this away. One fascinating study Klein quotes found that “priming white college students to think about the concept of white privilege led them to express more racial resentment in subsequent surveys.” Anti-racist indoctrination actually feeds racism. So tribalism deepens.
