I’m not sure what you’re suggesting with this link...there’s only a few things in the presentation I would take issue with. Namely, Lincoln’s justification to go to war with the States. The issue of slavery was an despicable and abhorrent stain on our history, there is no denial of this. But there was an actual Constitutional remedy to this; an Article V Amendment (cue music...”but that would have been so difficult!). But no, we couldn’t do that, we had to shoot and kill 400,000 people and destroy countless billions in property. I don’t recall Great Britain going to war against itself to end slavery or am I missing that part of history.
Additionally, that wasn’t even Lincoln’s stated reason for going to war; it was to preserve the Union which again, there simply is NO delegated power, from the consent of the governed, to “preserve the Union. None, nada, zip. Of course there is no authority to arrest State legislators, or suspend habeas corpus or arrest and imprison political opponents or a former Congressman (all inconvenient truths).
So, I generally agree with his teaching on natures law and the Declaration generally...but have serious objections to his understanding of Lincoln.
There was no slavery in the British Isles proper. The only slavery they had in the empire was on small islands in the West Indies where the slave owners had no power to resist and the 'freed slaves' had no ability to go elsewhere. Their only option was to go back to the same jobs. Nothing changed in reality.
It was a far different situation than in the United States.
