The photo above exemplifies what all the Freedom Rides and bus boycotts and sit-ins and marches were about. A simple thing. An ordinary choice to be comfortable as one goes about his day. A man -- in this case, a black man who happens to be president of the United States -- sits in the front half of a bus.
This is all you need to know about civil rights.
When you find yourself getting discouraged about how slowly things change, think of this photo. Then look at the one below, taken in 1956, a year after Rosa Parks refused to sit in the back of a bus in Montgomery, Alabama, on December 1, 1955.
