Toni Morrison, in a 1975 lecture, quoted by Ketanji Brown Jackson in her new memoir, “Lovely One”, which I’m reading now:

The function, the very serious function of racism … is distraction. It keeps you explaining, over and over again, your reason for being. Somebody says you have no language and so you spend twenty years proving that you do. Somebody says your head isn’t shaped property so you have scientists working on the fact that it is. Somebody says you have no art, so you dredge that up. Somebody says that you have no kingdoms, and so you dredge that up. None of that is necessary. There will always be one more thing.
