Former Supreme Court Justice Anthony Kennedy, an old white guy, worries that today's intellectual environment thwarts dissenting opinions. Egocentrism places one's opinion above all others that dare to differ. He's right. But he's old and white so...ignore everything he says. Old white guys, often assumed to be evil, have privileged cluelessness. Just stick to shouting down anyone with whom you disagree. It's working so well for us. And you know everything already. So keep screaming.
