Good grief, people.
Is this an example of the unnecessary suspicion and faulty logic that we will be dealing with for the next 4 or more years just because there is a black president? Let's get over ourselves.
I like Billy Graham and this is most likely because of his age and health rather than not wanting to mentor a black president. Billy Graham has been loved and respected by black people (and vice versa) for decades. In fact, there is still material on Billy Graham's take on racism and prejudice floating around if people want to read it.
