Technically, the Founding Fathers were traitors, terrorists, criminals, and all the other things you have mentioned. They knew that they were, and fully expected to be hanged as such if the whole enterprise failed, as subjects of British Law who had wantonly broken said law. We can argue that they morally in the right to act as they did, and that could go either way, but the fact is that they were breaking the law.
Technically speaking, the traitor, criminal, etc. appellations only apply if you are on th losing side. If you are victorious you become a hero, a liberator, a Founding Father, or whatever term you or history wishes to bestow. That is one of the constants of history. For example, what would Oliver Cromwell be called if he was on the losing side of the English Civil War?
The greatest crime a man can commit is treason against his lawful soverign; unless he wins.
But I am very interested in finding out what was the real root motivation of the American Revolution. I was taught, and they are probably still teaching, that the reason for the revolution was "Taxation without Representation".
However, as I got older, wiser (sic) and less naive, I realized that I am taxed fairly heavily and I do not feel that I have a real say in these taxes. But, my taxes are not too onerous and I do not think that the taxes on the American colonies were onerous or oppressive. And I am unwilling to take up arms because of my taxes, nor am I willing to send my children to the barricades for these taxes either.
From my viewpoint, taxation without representation is insufficient motivation to risk life and limb and all your possesions.
Hunger, starvation and other major economic shortfalls are sufficient reason for a revolution, which were among the primary motivations of the French and Russian revolutions. But this did not exist in America in the 1770's.
So I am at a loss to figure out how the Founding Fathers motivated the public into a revolution.
The slavery agenda presented earlier does not hold up to the light of day. Slaves were very rare in the revolutionary hotbeds of Boston and Philadelphia.
Anyone have any answers? I've got some theories, but that is all they are. The theories are economic, but they have a problem in that I still cannot figure out how they were applied so that the common man was motivated to commit treason.
