Desiree Cormier - Creole, Colored or Black?

Cormier, raised in part by her civil rights activist grandfather, identifies as African American, or, black.  So why does everyone in Pretoria tell her she's not black at all, but instead, "colored"?  And how does she persuade our government to stop considering Nelson Mandela a terrorist?  Also hear how she comes to dance to Pata Pata during Barack Obama's state visit.
