The dissemination of extreme nationalist ideas, especially through film and television works, involves ethical and legal issues. However, in theory, there are some ways that may have an impact on the audience's values: 1. **Narrative control**: By choosing a specific narrative frame, the country or a certain ethnic group is portrayed as noble and impeccable, while other ethnic groups are portrayed as antagonistic or inferior. 2. **Historical adaptation**: Using artistic processing of historical events to only show the favorable side of a certain ethnic group and downplay or ignore negative information. 3. **Character creation**: Setting up heroic characters to have specific ethnic characteristics, thereby associating these characteristics with positive images such as justice and strength. 4. **Use of symbols**: Visually and auditorily strengthening the display of national symbols, such as national flags, national anthems, traditional costumes, etc., to arouse the audience's sense of national identity. 5. **Language and style**: Strengthening the sense of national superiority through specific rhetoric and language styles in dialogue, suggesting that certain values are more important than other cultures. 6. **Psychological effect**: Using repetition and emotional resonance to subtly make the audience accept specific views and emotions. It is important to note that these approaches should be approached with caution as they may cause social conflict and cross-cultural misunderstandings. The purpose of discussing these strategies should be to better understand their impact and promote diversity and inclusion, rather than encouraging the spread of extreme ideas.
