I bet if the situation were different, and the school was teaching right-leaning material, this buffoon would be croaking a different tune.
As a matter of fact, that is exactly what happened and now kids are being churned out of school knowing nothing about anything.
Excellent point regarding past education battles. One can think for only a moment to dredge up memories of conflict over Bible readings, prayer in schools, evolution, pledge of allegiance, Mark Twain, Dr. Seuss, etc.
