My heart is with Charlie Kirk’s family, and with the United States. Politics has become a disease in this country, and it’s deadly. But don’t listen to the pessimists who say there is no cure. There is a cure. It is inside of us. We must find our better angels and walk back from the extremes. If we can’t agree on anything else, we must find agreement that we don’t solve our debates with violence. This is a horrible tragedy. May it also be a moment for everyone to rediscover their humanity.
