It depends entirely upon where on the history timeline one places a marker. Our founders didn't just up and decide it was time for a new independent government. They suffered a long train of abuses and usurpations before there was an inkling of consensus upon a new nation. They were just men before they were "founders". At a point in time before they decided to band together and declare independence from the King and an intent to form a new nation, they just were just men who wanted the King to stop trampling their rights, dignity, and English common law.
True. John Adams successfully defended the six Boston Massacre lobsterbacks on trial for murder, and was vilified for doing so, even though he viewed his trial work as "one of the most gallant, generous, manly and disinterested Actions of my whole Life, and one of the best Pieces of Service I ever rendered my Country."
But it must be said, the colonials didn't like paying taxes (wow, now there's a novel concept). The Crown was taxing the Colonies due to the cost of protecting them from not only all the native Indians roaming about creating havoc, but also protecting them from the French; the cost in using the British Navy to protect American shipping wasn't cheap, either. I think if the Colonies had been allocated MP's in Parliament, they would not have been able to use that rallying cry, 'No taxation without representation!' But because the colonials felt they had no say in their governance as they were voiceless in Parliament and the Crown appointed all the Royal Governors, we ended up where we are.
