"Politics" is a shaky, fluid concept. For example: Talking about a date I went on would be political to a sizable subset of most communities because of the genders involved. Drawing the line there while others are able to speak about their lives freely would alienate a large part of your community.

Politics is not an innocent team sport with few/no consequences for the losing side. Figuring out where to draw the line requires a deep understanding of what is politicized and why.
