Lincoln, unlike modern south-haters, knew that only a small precentage of southerners owned slaves. Work was nothing new to the white population of the south, but that claim does have a continued popularity among the culturally marxist.
In some states close to half of all families had slaves. In the south as a whole around 1 family in every 5 held slaves, and these were the people who would have to root or die. The benefits of slavery were far more common that you are apparently willing to admit. You would rather call people marxist and go home.
And only a small percentage of Germans worked in concentration camps during WWII. What's your point?
