'The Constitution's "Full faith and credit" clause, Federal Supremacy, and a "law of the land" legal tradition is how the "New Yorker in New Jersey" issue is handled.'
Very cute; so because it is now catered for under current legal doctrine, the clear issue is put to bed. Whereas the clear legal doctrine of the day - that the Crown in Parliament was the supreme ruler of the territories of the Crown - is not acceptable. Funny that.
"There's also the matter of the Social Contract, binding everyone to the outcome of a vote. Britain broke the contract, rescinding rights already possessed and imposing laws from afar, cutting the colonists out of the decision making process."
At the time Britain made no particular claims to be 'democratic' with 'rights'. The 'rights' were only ever what the law defined by the Crown in Parliament granted - or took away. What you are appealing to - the 'Social Contract' theory - was a new, self serving belief that suited the rebels of the day, along with their support for chattel slavery. It may well be progress that Lockean Social Contract theory has become more popular and chattel slavery less, but BOTH are disputable political / moral theorems.
"Keep in mind, the colonists were British citizens, and had all the rights that entails."
Hmm - dubious. Given the undemocratic nature of the Parliamentary electorate of the time, their rights were quite circumscribed.
' When Britain ceased treating them as citizens, well, the Declaration of Independance covers the response, it's legal and philosophical justification, and lists the grievances that motivated it.'
It offers a figleaf of self justification based on a conveniently self serving modern political philosophy. Marxism is equally a modern political philosophy; most of us wouldn't want to live under an implementation of that, especially one of the Leninist school.
I note you ducked: 'For the record, the Supreme Court rejected the claim of a non-citizen of the USA about not paying taxes quite early in the days of the Republic. Funny that...' as well as my little rant about the consequences of the American rebellion. The most important lesson from history is that we all have skeletons in our cupboards, and there are very few unambiguously positive events in history. Failure to recognise this is a form of idolatry, and like all idolatry, will lead you away from the truth.
