If the south had won, a lot of the changes that took place and opened the door for more people of color & women to move forward, would either have never occurred, or would have occurred much later.
If it were just a case that white men just wanted to maintain all of the power, then they could have held on to that power, if that was their true desire. But it obviously wasn't, for white man fought against white man to live up to the ideals the founding fathers had envisioned with all men being created equal in the eyes of the Lord.
Basically this woman is a Marxist eschewing Marxist Theory to create division.
That was the true desire in the South after the Civil War and into the 20th Century. The North got tired of fighting and went along with it.
Her major problem is that she is viewing the past through today's eyes.
I think that's generally true. You weren't going to see the kind of efforts made in the 1860s and after that were made in the 1960s and after. People's minds just weren't in the same place, and the rising idea of Darwinism encouraged the already strong belief that the races were fundamentally different. A century later, Hitler and Holocaust had convinced America that things had to change.
White men fought against white men to prevent Negroes from moving north. The North, with some but not really very many notable abolitionist exceptions was motivated by a purer kind of racism than the South. In the South there was economic motivation to retain the peculiar institution. In the North there was an interest mainly in the immigrant community to restrict economic competition from Black labor. Those folks did not have much social or political power. Among the wealthier folks with power they cloaked their social disgust at the impoverished and ignorant Blacks they didn’t want anywhere near their wives and daughters with a thin veneer of abolitionist intent. The real intent og both these classes was to keep the Negro as far away as possible. They certainly did not want them fleeing to te north in numbers which is what began to happen.
