Thanks for your link, I read your review.
Clearly, a key link in the chain of our Lost Causers' "logic" is the claim that Crazy Roger's Dred Scott opinions represented a valid interpretation of our Founders' Original Intentions.
They didn't, certainly not our Northern Founders, nor have I ever seen quotes from Southern Founders which confirm that their views in any way matched Crazy Rogers' Dred Scott ruminations.
No matter how much you hate it and no matter how many insults you spew at Chief Justice Taney, the fact remains that like it or not, Dred Scott was the opinion of the majority of the SCOTUS and as such was the law of the land.
