So we can all appreciate our own identities, our bloodlines, our beliefs, our backgrounds -- that tapestry is what makes us who we are. But the history of Africa -- which is both the cradle of human progress and a crucible of conflict -- shows us that when define ourselves narrowly, in opposition to somebody just because they're of a different tribe, or race, or religion -- and we ignore who is a good person or a bad person, are they working hard or not, are they honest or not, are they peaceful or violent -- when we start making distinctions solely based on status and not what people do, then we're taking the wrong path and we inevitably suffer in the end. This is why Martin Luther King called on people to be judged not by the color of their skin but the content of their character. And in the same way, people should not be judged by their last name, or their religious faith, but by their content of their character and how they behave. Are they good citizens? Are they good people?
