That's a real "chicken or the egg" quandary, isn't it? Are they "stuck in the 3rd Century" because they think "that way," or do they think "that way" because they're "stuck in the 3rd Century?"
Not to put too fine a point on it, I think the "3rd Century" analogy is giving them way too much credit, being far too generous.
They are actually stuck somewhere between "homo erectus" and "Neanderthal," possibly "Cro Magnon." Actual Stone Age cave-men, and I'm not trying to be glib or cute. These dismal abysmals have no place in modern society, and the world as it exists today cannot afford to continue to pat them on the head and coddle them for too much longer.
Doing so will absolutely result in a massive, brutal global conflagration, and we'll have only our spineless "political correctness" to blame.
