Black isn't a nationality. Black people in the US belong to the same nation as white people in the US. Nations have national anthems, not skin tones. The Star Spangled Banner, is as much the national anthem of black US citizens, as it is white, brown or yellow - because they are all part of the same nation. If you're going to be so racist as to suggest you can't share the same national anthem as someone of another skin colour - well, frankly, why don't you **** off back to your own country.. go and salute the Somalian national anthem instead
No, I'm not raking through history to 'provide links'. If you can't directly dispute a point, then question your own links.
