Barack's rendering of Mandela's quote is definitely more relevant than ever. It is difficult to "unlearn" what you may have lived or been taught. If the people you look up to and idolize are constantly giving you the wrong messages, it's harder to not learn the message than it is to learn it.  Please tell me though, what messages are being conveyed to anyone, white or black, that will listen to the garbage that is "hip hop" or rap. The music condones violence, murder, illegitimate children, killing whitey, shooting cops, etc., etc..  How can AA unlearn this mentality while at the same time idolizing it?
