What do folk think about this Anthem?

An Anthem that some say is divisive: https://www.youtube.com/watch?v=_Rn4Xh99dd4    Lift every voice and sing.  Sang in The States as an Anthem for Black People. If, though, it becomes International for all folk who have been oppressed everywhere, it could be until the World learns better. I first heard about it on Aljazeera this morning and have played it a lot I like to think that I've always been shoulder to shoulder with all peoples.
