What they are more fundamentally trying to protect are the black votes which are essential for Democrats. For that, blacks must be constantly depicted as under siege from whites, so that Democrats can be seen as their rescuers.
Promoting paranoia translates into votes. It is a very cynical political game, despite all the lofty rhetoric used to disguise it.
Whether the current generation of black students get a decent education is infinitely more important than whether the current generation of Democratic politicians hang on to their jobs.
Too many of the intelligentsia -- both black and white -- jump on the statistical bandwagon, and see statistical differences as proof of maltreatment, not only in schools but in jobs, in mortgage lending and in many other things.
Some act as if their role is to protect the image of blacks by blaming their problems on whites. But the truth is far more important than racial image.
Wherever we want to go, we can only get there from where we are. Not where we think we are, or wish we are, or where we want others to think we are, but where we are in fact right now.
But political spin and pious euphemisms don't tell us where we are. After a while, such rhetorical exercises don't even fool others.
If we don't have the truth, we don't have anything to start with and build on. A big start toward the truth would be getting rid of the kinds of statistical hoaxes being promoted by Secretary of Education Duncan and Attorney General Holder.
