This National Anthem protest stuff goes back to the 1968 Summer Olympic Games. It caused a stir then, and this new is just recycled attention whoring.
The 1968 Olympics Black Power salute was a political demonstration conducted by African-American athletes Tommie Smith and John Carlos during their medal ceremony at the 1968 Summer Olympics in the Olympic Stadium in Mexico City. After having won gold and bronze medals, respectively, in the 200-meter running event, they turned on the podium to face their flags, and to hear the American national anthem, "The Star-Spangled Banner". Each athlete raised a black-gloved fist, and kept them raised until the anthem had finished. In addition, Smith, Carlos, and Australian silver medalist Peter Norman all wore human rights badges on their jackets. In his autobiography, Silent Gesture, Smith stated that the gesture was not a "Black Power" salute, but a "human rights salute". The event is regarded as one of the most overtly political statements in the history of the modern Olympic Games.[1]
