Knowing these techniques is a shield. Words are used to peg people into one hole or words are used to make people fit into a pattern. Hitler used this propaganda in all of his speeches to convince the people that the Jews were not worthy of humanity. He even convinced the teachers in the public schools to humiliate the Jewish children as ones who could not think as well as others and often chided them by saying that their brains were smaller than others. Orientals are better artists.
Girls are better students.
Aryans are smarter because of their blonde hair and blue eyes. This technique promises something which will not live up to the promise. One of my favorite commercials shows the kids drinking a certain brand of hot chocolate and the promise that a snow will come as they drink it. Then the students will produce a slide show to share the information on Hitler's techniques and how he used them. The whole class may move from one computer to another to read the information in the slide shows.
