Unfortunately, culture diversity, sex ed, global warming, save the rain forest, tolerance, etc are the subjects that have taken up the time in classrooms for the last 30 years that I know of. We were always shocked when the kids came home touting the last propaganda. It was a difficult struggle to teach them to weed out the facts and keep them focusing on the important things. Now we are reaping the crop of brainwashed adults who haven't a clue about how and why this country had worked so well for the first 200 years (if that many).
