Here's a short, but very interesting interview concerning racial classification issues in schools. I can attest from personal exposure to schools in such environments that the problem is all too real.
One hopes the present Administration will do something to sort out this mess . . . but what? Its hands are too often tied by state and local officials who won't budge from their politically correct positions.
All I can say is, if your child is trapped in a school like that, get him or her out as soon as possible! If there are no better alternatives, think about home-schooling. It may be the only way to save them.
