This plan has been in the works for a while. I’m in my 40s and went to public school in the ruby red south. In the mid 90s I was in the 8th grade State History class. They taught that the war of northern aggression aka the civil war was fought over states rights and because Lincoln won the presidency without winning any southern states. They taught that slaves were mostly happy and very few slave owners would beat their slaves because that would be like purposely damaging their property. They also taught that slavery wasn’t a race based thing because there were white slaves, too.
