History teaches us that people believe what they want to hear.
Lies can sound so true when people are starving for truth.
Even whole societies will feast on their promises. The Inquisition was based on the lie that some people could force other people to change their religious beliefs. American colonists believed the lie that people of one race had the right to own, buy and sell people of another race. More recently, hundreds of thousands of people believed Hitler's lie that the Jewish race should be eradicated. Most of us can hardly imagine that anyone could have believed these lies.
