Adolf Hitler, the Supreme Chancellor during the Third Reich in Nazi Germany - he made a statement, he said “Make the lie big. Make it simple. Keep saying & Eventually the people will Believe it”. Now think about that.
You have to make lie big, it has to be about something about every thinks about/ everyone values in life. It has to be about general concepts that people accept, that people take into themselves and then base their life upon.
Hitler's Minister of propaganda during The third Reich was Paul Joseph Goebbels and and he made a statement that is actually even more more sinister. He said, "The bigger the Lie, the more it will be believed."
These men may have been evil, but they are speaking the truth.
