The title is misleading, just like the comment from the submitter: "Mongoloian idiocy" inappropriatelly suggests Down's Syndrome has something to do with Mongols, whereas early researchers thought people with Down's resembled Mongol faces.

So while one could apply the comment to the term-treadmill on "idiot", "retard", "moron", etc, the article has no support for it and is a case of inappropriate name in the first place.
