That's a fair point. I could have used less definitive language. The concept of objective vs. relative truth, or even whether such a thing exists, is a philosophical discussion I didn't mean to broach. And I certainly did not mean to imply there was a single correct opinion on all topics.

I simply meant to summarize my concerns with equating diverse opinions with inherently healthy discourse. While many topics can, as you noted, have a plethora of valid opinions based on perspective, they can also have opinions simply meant to "poison the well," as it were (or simply be wrong regardless of perspective). Climate change deniers being given equal time and weight on the news, for example.

Perhaps it would have been better phrased: "Diversity of opinions has no direct correlation with accuracy, sincerity, factuality, or value."
