It is unbelievable to me that anyone who is paying attention would support doing this to a fellow human being.
Mass behavior, not individual conscience drives this. The only news that sells is bad news. And fear is a strong motivator. So people vote their fear based on bad news. For example the recent event in France may push the Le Pen wing into the French presidency ... aka like Sarkozy was the French Bush Jr ... but Ms Le Pen could be a French Hitler.
On the Mormons ... an unpublished speech by Joseph Smith, is that the US would become a monarchy ruled by a Mormon king (a kind of early Branch Davidian messiah).
