jeffersondem: "You have made quite an issue of the term “\'necessary.'
In your sober judgment, who determined it was necessary for the colonies to declare independence."

I've answered your question now several times, but since you don't like my answer, you pretend I didn't answer, feigning deafness you call out, "what... what... what did you say?"

But perhaps you will take our Founders' words directly from them?
The word "necessary" or "necessity" appears four times in their Declaration.
This one should give you a sense of their thinking:

"But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.--Such has been the patient sufferance of these Colonies; and such is now the necessity which constrains them to alter their former Systems of Government."

"Necessity" in 1776 was a long train of abuses and usurpations.
No such abuses or usurpations existed in 1861, so Deep South Fire Eaters declared their secessions "at pleasure".

“The word “necessary” or “necessity” appears four times in their Declaration.”

So you are saying the people seeking independence, through their declaration, determined it was necessary?

OK. Sure. It wouldn't make sense for the King of England to have to agree it was necessary for the breakaway states to have independence. Only a fool would argue that.

I can buy into that. As did the American patriots in the Second War for Independence.
