The American colonies were in an odd place in that they were established by royal charters rather than any act of Parliament. When petitioning Parliament proved to be ineffective, the colonists tried petitioning George directly. And they'd suck up to George, telling him they're loyal subjects and while they're no fans of Parliament they love him. George basically replied, "I rule through Parliament, so if you love me then just do what they tell you." While some folks hated the monarchy for years, Thomas Payne I'm looking at you, anti-royal sentiment really didn't take off on the colonies until shortly before the fighting.
