So Lincoln provoked a war to end slavery? He and his regime were the only ones threatening slavery in the CSA.
"The same popular pressures that forced political parties to embrace the doctrine of **** demanded and sanctioned the social and economic repression of the Negro population. Racial segregation or exclusion thus haunted the northern Negro in his attempts to use public conveyances, to attend schools, or to sit in theaters, churches, and lecture halls. But even the more subtle forms of twentieth-century racial discrimination had their antecedents in the anti bellum North: residential restrictions, exclusion from resorts and certain restaurants, confinement to menial employments, and restricted cemeteries. The justification for such discrimination in the North differed little from that used to defend slavery in the South: Negroes, it was held, constituted a depraved and inferior race which must be kept in its proper place in a white man's society."
