In order to convince people of an extreme ideology, the plot usually needs to have the following elements: 1. **Emotional resonance**: The story needs to present strong emotional elements so that people can resonate with the characters. The pain, frustration or desire for the future experienced by the characters will lead the audience to emotionally identify with the ideology. 2. **Simple and clear enemies**: Extreme ideologies often depict enemies or opposites in a simplistic way. The plot can create a sense of urgency of "us versus them" and enhance a sense of unity and belonging through the depiction of characters, groups or systems. 3. **Turning and revelation**: The protagonist may experience a certain transformation, so that he "awakens" and accepts the ideology. This transformation usually stems from personal experience or is triggered by an important event. Such a plot can convince people of the necessity and correctness of the ideology. 4. **Utopian depiction**: Depicting an idealized society or group, highlighting the positive changes that the ideology can bring, and letting the audience see beautiful hope. Sometimes, the shortcomings of the current society and the bright prospects under the extreme ideology are presented through contrast to enhance its appeal. 5. **Strong beliefs or philosophies**: The story needs to have a systematic set of beliefs or philosophies to support the ideology. These beliefs can provide reasons for the characters' actions and convince the audience to agree. 6. **Personal stories and sacrifice**: Emphasizing the spirit of sacrifice in fighting for beliefs through individual stories and showing the personal price paid for following the ideology will create a strong emotional resonance and inspire others to identify with it. 7. **Social environmental factors**: The story should reflect a background of social unrest, instability or crisis, making it easier for people to accept extreme or unconventional views in order to seek solutions. Through the combination of these elements, the story can create a strong persuasive force, making it easier for people to accept and identify with a certain extreme ideology. Such a plot will not only attract the audience's attention, but may also have a profound impact on their thinking and behavior.
