Spot on.
Without digressing on Edward Gibbon, the Enlightenment, and
The Whig Interpretation of History, what they did to History, replacing it with
Social Studies, was a deliberate scheme to dumb people down so they wouldn't know any History and would not be able to figure out what was going on with the Fabian Socialist social engineering. The Carnegie foundation and the Deweyites of Columbia Teachers College figure in that.
For the "medieval" contribution to liberty and constitutionalism (and Magna Carta) check out "In the Meadow That is Called Runnymede" from the Acton Institute. Obama must have missed this part at Columbia and Harvard while he was being brainwashed in scientism, positivism, and utopian Fabian Socialism.
