Thanks for your recommendation, I'll check it out.
Our Lost Causers on these threads typically address this issue by first claiming it's just a Leftist lie to say Civil War was "all about slavery".
It wasn't, Lost Causers claim, but rather was about Southern "States Rights" and that evil leftist Democrat Lincoln's plan to economically enslave the South.
Some further claim that slavery was dying a natural death anyway and would have, in due time, been abolished peacefully throughout the South.
In other words, our Lost Causers here don't usually defend slavery itself, but rather just attack Northern opposition to it as "unconstitutional".
Only one poster, DiogenesLamp, insists that not only was slavery constitutionally enshrined, but as so wisely expressed by SCOTUS Chief Justice Roger Taney, it was abolition which our Founders intended to make "unconstitutional".
Curiously, DiogenesLamp will not confess to supporting the Left's 1619 Project, but his condemnation of our Founders could hardly be less full-throated than theirs.
Absolutely Taney did change the reading of the constitution. But you won’t find “slavery” or “property in slaves” anywhere in the Constitution, rather unfree “PERSONS” which specifically destroys Taney’s claim.
Just read the myriad of Rebel newspapers that said if they couldn’t expand slavery it would die, so the South had a choice of a fast death via military emancipation or a slow death by a “cordon of freedom” that choked off its outside support while forcing the southern tyrants to open their censored mails and ports.
