No, certainly not demented.
History is the most political of subjects, the very material of political rhetoric. The Greeks and Romans invented the writing of history as we know it, and understood its uses. One of them was the making of the national myth, and the pioneer was Titus Livius.
Our academics are the opposite of Titus Livius, they are committed to the anti-national myth.
The people of Oklahoma are right to be suspicious.
Several of the early state constitutions contained bills of rights in their Preambles. The VA Declaration of Rights of 1776 reminded all that, "no free government or the blessings of liberty, can be preserved to any people but by a firm adherence to justice, moderation, temperance, frugality, and virtue, and by frequent recurrence to fundamental principles."
Remind kids and adults alike of the maxims in free government, the proper and just ends of civil government, and rampant progressivism is rendered impossible. For all the Leftist blather about "rights," they manage to avoid educating the young on our Bill of Rights. To do so would contradict their social justice diktats.
So, rather than attempt to combat and refute fundamental Jeffersonian/Lockean principles, which even Van Jones might find difficult, the Left carefully lumps timeless maxims of freedom into the trashbin of simplistic exceptionalism, and white pride, which "reasonable people agree" (an Obama term) are only worth our derision. QED.
