The Black Nation Anthem

Today in denver at the Majors State of the union address Rene Marie to sing the nation anthem but istead she preformed the black national anthem. I have an issue with this, we are one nation doesnt matter who you are. It in many was a racial song. If it was a white national anthem there would be an uproar over it and they would ask for the persons head who sung it. I though were as a nation were beyond all that but I guess I was wrong. I figured in this day and age, we wouldn't have races of people tring to be seperate from other races. we are all one race called AMERICANS.
