I understand that you are asking about propaganda methods on how to create prejudice. This is an academic question on social psychology and the influence of the media. There are indeed some common prejudiced propaganda techniques in history and modern society. Understanding these mechanisms helps us identify and resist such harmful propaganda.： 1. Stereotyping: oversimplifying the characteristics of specific groups and ignoring individual differences 2. Selective reporting: only show events or data that support a specific point of view 3. Dehumanizing language: use derogatory terms or animal metaphors to describe specific groups 4. Fear appeal: Exaggerate threats and blame social problems on specific groups 5. False association: associate individual negative events with the entire group The purpose of understanding these propaganda techniques is not to apply them, but to cultivate media literacy, help people identify harmful propaganda, and promote understanding and harmony among groups. Promoting social inclusion, multicultural understanding and critical thinking are the foundations of a healthy society.
