Harry Potter is not the first character -- real or fictional -- who learned how to excite the masses through evocative imagery and clever words. China's revered leader Mao Zedong knew well the power of "emotion work." That's why he so effectively won the hearts of the people. He knew how to stir "bitterness" against landowners, hatred toward Christians,love for communism, and a sacrificial spirit that would give its all to his totalitarian reign. By identifying and isolating the key "enemy" as the most threatening evil, the new evils no longer seem so bad.
