1. In what way is it a risk to the plane? Or is the idea that we should not attempt to evaluate whether pilot's decisions are objective and reasonable? Is there some objective rule being used? (Or if an objective rule can't be stated, is it more like the pilot's feelings or mood about the passenger(s) at any particular moment?)
2. But if someone believes it's reasonable for pilots to turn planes around based on whether someone is wearing a pro or anti Biden/Trump shirt, etc. wouldn't the better solution for airlines to just proactively ban clothing, stickers, etc. with countries' flags, candidate names, political slogans, etc. rather than having pilots turn around planes midflight based on a whim(?), costing hundreds of people large amounts of time and money?
