The term that best describes your viewpoint or stance on a particular topic, often referred to as the central theme, is "position" or "thesis."

• Position : This refers to your specific opinion or stance on an issue.
• Thesis : In writing or argumentation, this is the central idea or main argument you are presenting.

If you mean the overarching idea or message, "theme" is also commonly used, especially in literature or discussions about broader topics.
