Our conclusion in our impromptu book club was that made sense: why would the state schools give students lots of examples of how violence against the state was an effective negotiating tool? It was extremely jarring to reconcile with the image of US history we'd been imbued with up to that point, which of course was also a reflection of our socioeconomic status at the time.
As a counterpoint, "The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants" is also taught in schools, so it's possible I'm just selectively remembering things.
