The old lie that the civil war was not about slavery.  The articles of secession for the state of Texas specifically state the goal of seceding included the maintenance of slavery and the supremacy of the white race.  And the post ignores that as the south "evolved" millions would have remain in slavery, beaten, starved, raped and sold by their owners.  The death toll for the civil war, by the way, was 600,000.  Not millions.
