So they kept them in slavery? That is a non-sequitur. Obviously they didn't accept this concept as a "Universal Truth" in 1776.
But it was the later South who rejected the idea of natural rights (which you claim they are claiming) saying that the Declaration was only for White men.
You don't seem to be grasping the fact that this is exactly what the Founders believed in 1776. Again, they didn't let any of their slaves go.
The Founding Father's for the most part hated slavery and had every intention of ending it.
No they didn't. Jefferson never let his slaves go. Washington made provisions for manumission of his slaves upon his death, but while he was alive, he kept them. Stop trying to force history to conform to what you want to believe.
That is why they had no problem with acknowledging the truth of the Declaration of Independence.
No they didn't, but the person who's having a problem with acknowledging the truth of the Declaration of Independence is this person who is arguing in 2016 that it applied to slaves.
No it didn't, and the evidence of this is so vast, you have to be a deluded kook to believe otherwise. The Declaration was *MADE* to apply to slaves later, (Starting in Massachusetts), but at the time it was written, it most certainly was not intended to do so.
Now if you chose to live on Gumdrop mountain and ride your Unicorn back and forth through the Cotton candy forest to the Chocolate river, I can't stop you, but if you want to be taken for a rational person, you need to stop pushing a made up fantasy as reality.
Gradually slavery was ended in many States.
What changed was the South's view about natural law and the Declaration of Independence, as typified in the Drew Scott decision!
But the VP of the Confederacy Alexander Stephens made it known that the Confederacy was going to be built on the rock of RACIAL INEQUAILTY, that is why the 'negro slavery' was written right into their Constitution!
Stephen's admitted that the Founder's had wanted to end slavery and were wrong to do so!
You, like so many Neo-Confederates, want to rewrite history and ignore the facts.
The South had no legal right to leave the Union.
Had Andrew Jackson been President instead of Lincoln, who was kinder, he would have hung the lot of them as traitors!
But not to be tedious in enumerating the numerous changes for the better, allow me to allude to one other-though last, not least: the new Constitution has put at rest forever all the agitating questions relating to our peculiar institutions-African slavery as it exists among us-the proper status of the negro in our form of civilization. This was the immediate cause of the late rupture and present revolution. Jefferson, in his forecast, had anticipated this, as the “rock upon which the old Union would split.” He was right. What was conjecture with him, is now a realized fact. But whether he fully comprehended the great truth upon which that rock stood and stands, may be doubted. The prevailing ideas entertained by him and most of the leading statesmen at the time of the formation of the old Constitution were, that the enslavement of the African was in violation of the laws of nature; that it was wrong in principle, socially, morally and politically. It was an evil they knew not well how to deal with; but the general opinion of the men of that day was, that, somehow or other, in the order of Providence, the institution would be evanescent and pass away. This idea, though not incorporated in the Constitution, was the prevailing idea at the time. The Constitution, it is true, secured every essential guarantee to the institution while it should last, and hence no argument can be justly used against the constitutional guarantees thus secured, because of the common sentiment of the day. Those ideas, however, were fundamentally wrong. They rested upon the assumption of the equality of races. This was an error. It was a sandy foundation, and the idea of a Government built upon it-when the “storm came and the wind blew, it fell.”
Our new Government is founded upon exactly the opposite ideas; its foundations are laid, its cornerstone rests, upon the great truth that the negro is not equal to the white man; that slavery, subordination to the superior race, is his natural and moral condition. [Applause.]
