In the old school days, the blackboard was used to record facts

Erma - In the old school days, the blackboard was used to record facts and to instruct students. When the process was completed, an eraser was used and the chalk information disappeared. In the new school days, facts are erased and history will disappear for future generations. The civil war monuments are being destroyed because that part of the U.S. history is not politically correct to the social engineers of one world order. The problem becomes who makes these decisions? When will it be necessary to replace Washington, Jefferson and others who don't fit into the new PC model?
