It's stupid to have to say Black Lives Matter. They more than just matter. They are essential. Could compare this to Gerald Callahan talking about the thymus and the immune system. The thymus has to let foreign bodies in to build the human body. The borders have to be porous. If they are not, then we get a very terrible disease called an auto-immune disease as the thymus attacks our own cells. Could racism be an auto-immune disease?
