Well, it actually kinda was "terrorism," and during the Revolutionary War, many American combatants were "insurgents." We don't call them that because they won, and shaped our history, but had they lost, they all would have been hanged, and our history books would refer to our founding fathers as subversive terrorists that sought to undermine the crown.
But to be fair, had I been alive during that time, I too would have been a "terrorist."
