While I am no fan of social movements built on false narratives, Black Lives Matter did inspire the Post’s valuable study — a study that, fairly read, should defuse national tensions. It won’t, however. The narrative is too strong, and too many powerful people have too much to gain by ratcheting up racial tensions. So Black Lives Matter will likely roll on, and still more black Americans will be taught to hate and fear law enforcement, fed on a steady diet of lies about their own country. America is a better place than they’ve been led to believe. Radical racial politics will only make it worse.
