No kidding. Back in June I didn't see one white person working the Metro or security in D.C. Black teenagers ran amok in the cars and the black security just ignored them. As the black ghetto bangers left the train they jumped the turnstyles and the black security just let them get away.
It sounds like the black people were discriminating on the basis of skin color which would make them racists.
However experts in academia have assured us it is not possible for a black person to be a racist. I must be mistaken.
