From Stanley Fish:
I flashed back 20 years or so to the time when Gates arrived in Durham, N.C., to take up the position I had offered him in my capacity as chairman of the English department of Duke University. One of the first things Gates did was buy the grandest house in town (owned previously by a movie director) and renovate it. During the renovation workers would often take Gates for a servant and ask to be pointed to the house’s owner. The drivers of delivery trucks made the same mistake. The message was unmistakable: What was a black man doing living in a place like this?
There are reasons why people sometimes explode.
