Three things are vital for understanding the thinking of the Founders who were Christian, which, contrary to popular legend, was most of them. (For instance, the majority of Colonels in the Continental Army(not the militia) were Presbyterian elders.)
1. The English Bill of Rights of 1689 granted most of the rights (at least to Protestants) that the US Bill of Rights set down (including the right to keep and bear arms). Among these laws, the King was made subject to the will of the parliament.
2. For most of the time between 1630 and 1763, the relationship between the Crown and the colonies was "benign neglect," and this accelerated over time. Each colony had an elected legislature, and the exact form of the executive varied according to the colony. The colonies were, for all practical purposes, self governing.
3. During this time, several generations of colonials had developed the same concept of representation that we have now--I am represented by Mr. X, and if I don't like him, I will vote to replace him in the next election. He is MY representative. The English concept (then) was: the King represents himself, the Lords represent themselves (in the house of Lords), and commoners in commons represent all the commoners, including the colonials. We said, "no taxation without representation." The Crown said, "silly people, you are represented by other commoners.
Because of the above, our founders could claim that the attempt to re-impose full royal rule without allowing direct colonial representation was tyranny. As now, we and the British were two people separated by a (supposedly) common language.
