Dear Annie: I could just opt out of family group chat, but should I school my cousin first?

A family group chat is being disrupted by a cousin who frequently posts political rants. While the chat can be useful or entertaining, it has become predominantly noisy and frustrating for other members. One relative is currently debating whether to mute the entire conversation or first attempt to educate the cousin on their behavior. The situation highlights the tension between maintaining family connections and managing disruptive digital communication within a shared group chat environment.
