Seems pretty evident now, just who is doing the indoctrination. The myth of the Great White Hope in the north riding on their white horses to save the poor slaves. Myth. Four Union states were slave states, Lincoln himself states that slavery was fine if it meant keeping the union. Slaves were not freed at the conclusion of the Civil War in Union states. The Constitution of the United States had to be amended in order to do that. The Emancipation Proclamation was a wartime proclamation with no force of law outside of states in rebellion, which no longer recognized US law in the first place. So, that wartime ploy to foment slave rebellion in the Confederacy was enshrined for what reason? It fed the myth.
If you wish to believe that, be my guest.
Why do you keep propping up all those strawmen? No one here is making those claims - except you.
