There are many ways to use propaganda to create prejudice and hostility towards a particular ethnic group or group. Here are some common methods: 1. **Stereotypes**: Emphasizing the negative characteristics of an ethnic group or group by conveying simplified and one-sided descriptions, thereby causing misunderstandings and prejudices. 2. **Fear mongering**: Using fear psychology, such as emphasizing the threat that a certain group poses to social security, economy or culture, to stimulate hostility. 3. **Selective information**: Spreading only negative news or events about a certain group, ignoring its positive contributions, thereby creating a one-sided view. 4. **Social media manipulation**: Spreading hate speech, conspiracy theories and false information through social media platforms to quickly spread hostility towards a specific group. 5. **Images and symbols**: Using images or symbols with strong emotional impact to intensify negative emotions, such as associating a specific group with negative phenomena such as violence or crime. 6. **Political propaganda**: Some political forces may use nationalist sentiments to enhance supporters' sense of solidarity by portraying the opposition between "us" and "them", while increasing hostility towards other groups. 7. **Historical distortion**: distorting historical facts and emphasizing the historical violations of one ethnic group or group against other groups as a basis for current hostility. These propaganda methods are often intertwined and can quickly influence people's attitudes and behaviors. Therefore, it is very important to maintain critical thinking and an open mind when facing this information.
