Thought control is a very difficult task. It always has been. The Inquisition, Nazi Germany, the Soviet Union, and the People's Republic of China tried but three of the four are no longer with us. Short of totalitarian controls, thought controls will be ineffective. And totalitarian controls are difficult to impose these days.

While thought control is difficult, one cannot ignore the damage done trying to do it. All of the above examples were expensive in terms of human suffering and death toll for long periods of time. The controls were effective for some time with long periods for recovery. The facists may lose in the end but the price of victory is very high. I fear the current and future efforts at controls will be costly no matter what the outcome. bob
