John Dewy comes to mind as a major representative of progressive education and liberalism "John Dewey developed ideas of evolutionary democracy and evolutionary education and evolutionary law." Actually Dewy was all over the map as a "modern thinker" ... our public education system was his platform for many of his "experiments in humanism" which discouraged bed rock values.

It’s based on anti-colonial Marxism.
