“If you’re referring to the “excited domestic insurrections amongst us” to mean slave rebellions, well, there is a lot to dispute in that.”
There is no dispute about the meaning of the reference, unless you have invented one.
"I believe the declara[tion] that 'all men are created equal' is the great fundamental principle upon which our free institutions rest; that negro slavery is violative of that principle; but that, by our frame of government, that principle has not been made one of legal obligation; that by our frame of government, the States which have slavery are to retain it, or surrender it at their own pleasure; and that all others---individuals, free-states and national government---are constitutionally bound to leave them alone about it. I believe our government was thus framed because of the necessity springing from the actual presence of slavery, when it was framed. That such necessity does not exist in the teritories[sic], where slavery is not present." The Collected Works of Abraham Lincoln edited by Roy P. Basler, Volume III, "Letter to James N. Brown" (October 18, 1858), p. 327.
"We were proclaiming ourselves political hypocrites before the world, by thus fostering Human Slavery and proclaiming ourselves, at the same time, the sole friends of Human Freedom." The Collected Works of Abraham Lincoln edited by Roy P. Basler, Volume II, "Speech at Springfield, Illinois" (October 4, 1854), p. 24
"I hate it because of the monstrous injustice of slavery itself. I hate it because it deprives our republican example of its just influence in the world." The Collected Works of Abraham Lincoln edited by Roy P. Baslero
On the contrary, here is a link to an article that makes a very good case that the meaning of the phrase is not what you claim: The "Domestic Insurrections" of the Declaration of Independence
