This wasn't supposed to be about opinions and viewpoints. But I think this notion of "sufficiently bad as to cause potentially intolerable damage to the site" extends not only to technical "answers" but to opinions and viewpoints as well.

Please keep in mind that this "crap shroud" (or whatever we want to call it) only affects the appearance of the site to anonymous monks. So "minority viewpoints" will always be visible to the logged-in; and will of course be visible even to AM until the node rep hits some abysmal threshold.
