This is not the default mode of browsing facilitated by HN, so the system inherently lends itself to killing contrarian perspectives long before there can be any meaningful discussion about them.

To me, there’s nothing more powerful than someone posting a contrarian perspective and there being a highly upvoted, well-reasoned/cited response as to why the contrarian perspective isn’t valid. This I would prefer over having those contrarian perspectives suppressed, and I never get to see or engage with them.
