The problem with our contemporary culture isn’t that people can often be callous and irrational. That’s our lot as imperfect creatures. The problem is that we seem to have given up the idea that we can do any better.
In fact, being callous toward others seems to be increasingly worn as a badge of honor. It can be a form of powerful moral grandstanding to be callous toward a particular group of others. Even our entertainment often celebrates individuals who obtain what they want through callousness to everyone else.
Many white Americans have a cultivated callousness toward black Americans, demonstrated most recently after the acquittal of the police officer who killed Philando Castile. Although this case also has to do with structural legal issues that make it almost impossible to convict police officers, I see no sense in denying that responses would be different had Castile been white, especially from white Americans who say things like, "He didn't comply!" (with the implication that he thereby deserved to die) or the NRA's near silence in a case that ought to be a rallying cry for Second Amendment defenders.
