Detaching flamewars so that they languish at the bottom of the page is standard HN moderation and the reason we do it should be obvious. If you don't want that to happen, nothing is easier to avoid (from a moderation point of view): simply provide corrective information respectfully. Of course that is not so easy from a personal frustration point of view—that is something every HN user (certainly including me) has to work at.

I definitely don't want to penalize your counterarguments, but if you can't or won't decouple them from guidelines-breakage, what choice do we have? We do just the same with users and threads that are arguing the opposite.

There are two very different issues here: (1) Wayland; (2) protecting the commons. Important as the first one is, the second has to take precedence because it affects every topic, every thread, and the survival of the community.
