The national debate over teaching of history, particularly about racism, brings to mind efforts in the former Soviet Union or modern Communist China to erase history, muzzle citizens, burn books and rewrite school texts to reflect what one group wants while ignoring others.

Parents who complain about children feeling uncomfortable reading about racism need a history lesson themselves. Only through discomfort do we grasp that Americans have suffered atrocities simply for the color of their skin. Only through understanding it do we end it.
