By midcentury this antislavery movement had gone into politics and had begun to polarize the country. Slaveholders did not consider themselves egregious sinners. And they managed to convince most non-slaveholding whites in the South (two-thirds of the white population there) that emancipation would produce economic ruin, social chaos, and racial war. Slavery was not the evil that Yankee fanatics portrayed; it was a positive good, the basis of prosperity, peace, and white supremacy, a necessity to prevent blacks from degenerating into barbarism, crime, and poverty.
