‘Letting the Southern states have the independence’....
Really, how about the lives of enslaved people?
Democrats are always deciding what race, age or type of human is really a person. Don’t be a Democrat.
Since it wasn't a problem while the Southern states remained part of the United States, it shouldn't have been a problem when they went independent. Indeed, not only did there remain five slave states in the Union during the war, but Abraham Lincoln and the entire Northern portion of the Congress voted to make slavery permanent by passing the Corwin amendment through both houses of congress.
Trying to tell me someone was concerned about enslaved people *AFTER* they voted to keep them enslaved forever is just blowing smoke up people's @$$es.
