It wasn't really a German effort, it was imposed upon them by the victors after an unconditional surrender and the disruption of any remaining form of Civil Government. Even their current laws outlawing Nazi symbolism comes from the rules imposed on them.
The German government still allows memorials to the Soldiers who fought in the war, even SS units. The leaders are not memorialized, but again I still see a huge difference between people fighting for what they thought was their own country, even with their peculiar institution, and a country that was practicing genocide against one group, and planning for more if they managed to actually win the war.
Jews were only the first step,. Poles and Russians were next.
See this is where you lose me with the false comparisons. You bring up WW2 and call it genocide against one group and compare it to the Civil War that you describe as "people fighting for what they thought was their own country". You leave out the fact that they were fighting for the right to own people against their president and governments directives. Slavery is not as bad as genocide but it is still disgustingly bad, there were plenty of rapes and murders and abuses going on. It was a shameful element of our society and the the civil war was centered around it. These statues and confederate symbols represent those detestable values to many people. Just as Nazi symbols represented a disgraceful agenda and history that did not deserve to be celebrated through public monuments. Do you not understand that?
Actually they were fighting due to the chance of Slavery maybe being curtailed in the territories, and eventual, probably compensated emancipation. The South feared Lincoln like progressives fear Trump.
You also have to remember that Citizenship in a State was far more of an identifier then that it is now. People were often Citizens of the States first, and their Country second. To them, they were just exercising the same method of gaining independence that the Colonists did against the Crown. Now to me, you need the consent of the rest of the country before you can go, and that means war if they don't. Which is what happened.
Slavery was also waning at the time, but was still not universally condemned. Killing a whole people off "because they are an enemy" was recognized as an evil thing pretty much universally by the rest of the world when the Germans were doing it.
The difference still is Nazi symbology was removed at the time the other side won and imposed its rules. We have allowed the South to memorialize its lost cause and dead citizens for over a decade, now all of a sudden all that is evil evil evil. I'm sorry but I refuse to bend the knee to the chronically offended who if they win will just move on to the next idiotic request to assuage their own butt hurt.
