That strange. I was also studying history and couldn't figure out how Jim Jones got 900 people to commit suicide. He told them stories each day about the "enemy" coming to get them.I was studying History and couldn't understand how millions of people followed Hitler to their death beds so easily and then I watched the liberal Americans and had my answer.
So on their last day he told them the enemy was there. Fear of the "others" is how most leaders without power try and gain power. You Repubs practice this each day.
If you need an example of the fear game played at its best, just tune in to Rush, Beck or FauxNews for a day.
