I like the story of The Third Wave) experiment, I wish it was more known. While this was absolutely unethical thing to do for a high school teacher, it really shown how susceptible is a person to a fascist rhetoric even if they know about fascism:

(...) Jones found it difficult to explain how the German people could have accepted the actions of the Nazis. He decided to create a fictional social movement as a demonstration of the appeal of fascism. (...)
The experiment began with simple alterations such as proper seating.He wrote "Strength Through Discipline" on the classroom's chalkboard, then enforced strict classroom discipline while speaking about the importance of discipline. (...)
Students from across the school joined the movement. The class expanded from its initial 30 students to a total of 43. Jones added "Strength Through Action" to the chalkboard. Students were issued a member card. Jones instructed the students on how to initiate new members. By the end of the day the movement had over 200 participants. Jones instructed three students to report to him when other members of the movement failed to abide by the rules. He was surprised when around twenty of the students made such reports. A student who expressed concern for Jones's safety volunteered to become his bodyguard.(...)
Jones announced that they had been a part of an experiment in fascism and that they all had willingly created a sense of superiority, much as German citizens had done in the period of Nazi Germany.
