When writing persuasive messages, one way to avoid faulty logic is to avoid hasty generalizations
Thoroughly consider and address opposing viewpoints. By acknowledging and addressing opposing viewpoints, you demonstrate that you have considered all sides of the issue and are not simply trying to manipulate your audience. This can make your argument more credible and persuasive.
Don't straw-man the opposing argument by misrepresenting it or making it seem weaker than it actually is. By carefully considering and addressing opposing viewpoints, you can avoid faulty logic and make your persuasive messages more effective.
