OK, so -- the point of the article is not (1) whether astrology is a science, (2) that there are 7 continents, (3) whether the sun is bigger than the Earth, or (4) whether any of those are good filters on dates.
It's about the general principle that (a) OKC should make Mandatory questions only count as negatives, and (b) unless they do that, users shouldn't make "factual" questions including (1, 2, 3) mandatory.
