They surely don't! It's become pretty much impossible for a white who knows anything about American history to teach black students, unless he's willing to lie. The weird thing is, that as more and more information comes out about the grayness of slavery (black freedmen in the South, black slaveowners, virtual freedom, Northern racism, etc.), the ed commissars are imposing a victimological pseudo-history that veers ever farther into fantasyland, away not only from what is now known, but from the limited knowledge of, say, sixty years ago.
