Benjamin Franklin had early campaigning for colonial dissonance.
 In the wake of Somerset v Stewart, he voiced frustration at British abolitionists:O Pharisaical Britain! to pride thyself in setting free a single Slave that happens to land on thy coasts, while thy Merchants in all thy ports are encouraged by thy laws to continue a commerce whereby so many hundreds of thousands are dragged into a slavery that can scarce be said to end with their lives, since it is entailed on their posterity!Franklin, however, refused to publicly debate the issue of slavery at the 1787 Constitutional Convention
In London, Franklin opposed the 1765 Stamp Act
