I agree that artificially imposing a "fair and balanced" framework onto news/discourse is a bogus concept as, like you say, the centre of gravity can be shifted in favour of nonsense ideas just by posing the question.

But in your second paragraph, you seem to imply (maybe I'm wrong here) that there is a sense of objectivity inherent in news reporting, because the reporting leads logically from the facts. However, the facts are hand-picked, meaning bias is unavoidably baked into the premise. In which case we are no closer to avoiding "focussing on opinion diversity", as the same opinion diversity arguments apply to choosing the facts on which to report.
