 The song "Cool Considerate Men" is anachronistic; the terms "right" and "left" in politics were not in use until the French Revolution of 1789.John Dickinson, who is portrayed as an antagonist here, was motivated mainly by his Quaker roots and his respect for the British Constitution, having lived in England for 3 years in the 1750s.He was no wealthier than some members of the pro-Independence faction, and freed his slaves in 1777.
