The Thing About Racists
I am currently reading Blue Highways by William Least Heat Moon. It's a memoir about his travels around America—a genre that seems overdone if it weren't for the fact that there are at any time 300 million people to talk to with each person an ever shifting landscape. Currently (in the book) he's in the South and encountering all sorts of racist people. But also, some of them still have something compelling or kind about them—even if they have buried it beneath a pile of ignorance.
It's easier to reduce people to their worst qualities than pry the good out of them. So when you meet an ugly person. Keep digging.
