@ossobuco,
Ossobuco - many people are sensitive about being too tall or too short, or having pockmarked skin or barbed-wire hair, but you never hear any of these conditions preceded by "dehumanizing". Sensitivity cannot, therefore, be the issue.
Unless either the pesky troll(s) who entered the "dehumanizing" tag here and are marking posts up / down - as if that made the slightest difference to anyone - speak up to explain these weird activities, I'm inclined to think Sullivan hit upon a profound truth.
