Remind me again, when did the Confederacy attempt to exterminate entire ethnic or religious groups? While you're at it, maybe you can provide a list of sovereign nations the Confederacy invaded, looted and turned into puppet regimes. When you can do that, we can start taking the comparison of the Confederacy and Nazi Germany seriously. Otherwise, it just sounds like the sort of propaganda we get from BlackLivesMatter activists.
There's no legitimate comparison of Confederates with Nazis I can think of, except perhaps that both, let us say, bit off more than they could chew.
So have many others throughout history.
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.
