In the process of publishing books, if you want to hide extreme political positions so that they can sell well in the mainstream market, you can consider the following strategies: 1. **Neutral language**: Use more neutral and objective language, and avoid using words that may evoke strong emotional reactions. 2. **Balanced viewpoints**: Provide multiple viewpoints and let readers draw their own conclusions. This can make the book look more comprehensive and not just a promotional material for a single position. 3. **Backgrounding**: When dealing with sensitive topics, give sufficient background information to help readers understand the process of the author's position formation, rather than directly promoting extreme views. 4. **Character creation**: Express political positions in an indirect way by conveying views through fictional characters or storylines. This literary technique can reduce direct political colors. 5. **Storytelling**: Focus on telling a fascinating story, using political positions as background rather than core themes. 6. **Moderate humor**: Add humorous elements when appropriate to reduce the hard-line feeling of the viewpoint and soften the presentation of the position without affecting the overall tone. 7. **Target audience**: Clearly distinguish different audience groups and tailor publicity and marketing strategies to make the book more universally acceptable. 8. **Cover and Promotion**: When designing covers and promotional materials, highlight elements that are not directly related to extreme political positions to attract a wider readership. Through these methods, books can gain wider acceptance and success in the mainstream market without weakening the core message. At the same time, it is important to remain authentic to avoid being discovered by readers after publication and having a negative impact.
