Recently, on this same site, I reviewed https://meta.stackexchange.com/review/low-quality-posts/42346. That was a two-day-old discussion answer on a discussion question and required two Looks OK to dismiss, so it wasn't an auto-flag. And given the content, I can't see any way anyone who knows what Meta is for could sincerely flag that as either VLQ or NAA. (It's further suggestions for/amendments to a pending feature. How much more answer-y can you get?)
It's bad enough that we have to live with downvotes for disagreement as an unfortunate but natural consequence of using Meta for opinion-based questions (aka discussion). Using flags for disagreement are a whole nother story, and I for one find that pretty despicable. "I don't like what you're saying, so I'm going to ask some reviewers to delete it" is a really terrible way to go about policy decisions. And while we already discourage using flags for wrong answers on all sites, it doesn't seem that that's enough to prevent a fair number of flags for answers that are only subjectively disagreed with, policy-wise. (Although this does not appear to show up on any other site than M.SE.)
Can we actively discourage this in some way, perhaps simply through Meta consensus?
