I see the confederacy as Nazi-lite, they didn’t want to exterminate a whole race, just keep them as chattel.
And before the lost causers start screaming that America had slavery at it’s founding, most of the founding fathers were embarrassed and bitterly conflicted by it and hoped it would eventually die out. They were so embarrassed they wouldn’t even use the word slavery in the constitution. Thomas Jefferson went so far as to call it a “hideous blot”.
Not so the confederacy, they proudly proclaimed that blacks were inferior and their natural state was slavery. They proudly used the word slavery in their constitution and their Vice President proclaimed that this was the cornerstone the confederacy was built upon.
Why anyone would want to honor such a government is beyond me.
The Founding Fathers who opposed slavery believed that it would fade over time and be made obsolete by more economically efficient models of labor. This no doubt was true. With the exception of Hamilton, none of them was a radical abolitionist who would have used the power of Federal government to outlaw slavery. Lincoln didn’t start out as a radical abolitionist (he was a non-extensionist), but he certainly had the ear of his party’s radical wing.
However strong a temptation to compare Confederates with Nazis may seem, we here must resist it as not only unpolitical but also anti-historical.
Only in the fact that they both took on forces which, strictly in 20-20 hindsight, they had no chance to defeat.
Otherwise, 1860s Confederates were much closer to 1860s Unionists in character & beliefs than either were to Nazis, Communists or, indeed to today's leftists/progressives/liberals/Democrats.
If you're tempted to say, "well slavery was like the Holocaust", no! the opposite since the US slave population doubled, doubled again and redoubled between 1790 and 1860, even after importation of slaves was outlawed.
I have myself compared Confederate generals like Lee and Jackson to Germans like Guderian and Rommel, but only to say these were enemies who fought honorably and capably for what turned out to be a flawed & lost cause.
The South, by contrast, was led by people who demonstrated a sentimental attachment to their servant class, and were in turn treated with respect by the poorer members of their communities, both White & Black. Were it otherwise, the Confederacy could never have held together, much less hold off the North for four years.
Incidentally the Confederate States were represented by two Jewish Senators in 1860, at the time secession started. They were the exact opposite of either Communist or Nazi-lite.
Your error is in failing to acquaint yourself with the actual cultural context of the historic events. There is overwhelming anecdotal evidence of my points--for one interesting example, Stonewall Jackson--pre-war--ran a Sunday School for slave kids. It was no stretch, either, that Mammy in "Gone With The Wind" was a sort of ethical agent whose attitude towards other characters was a clear indication of whom was good & whom bad. Margaret Mitchell based the book on extensive interview with elderly people who had lived through the war.
