Basically this entire conversation boils down to "I hate the South" and revenge porn. Basically otl reconstruction was very successful. Why? Because as totally imperfect as it was, as messed up as it was, as unfair as it was to an entire race of people it worked. The nation endured and stayed together. There were no mass hangings, no land confiscation, no mass imprisonment. The nation went on to not only survive but thrive.
It's nice what people here want to do through the lens of 2021. What you want to do would have never have worked and we would be living in a worse world. The South (if even one of your ideas have been tried) would have devolved into something that made Northern Ireland and Beruit of the 80's look like happy places. Armed resistance would have gone on for decades if not for a century or more.
You would have had a escalating series of union soldiers being murdered and civilian reprisals. You can screw the planters all you want. You can not however take their education, their knowledge or their connections. Just like you can send blacks to Congress but you can not give them a education to read the bills that they are voting for. You try any of this revenge porn and you get Alexander's scattering to the hills like rabbits.
There is no way the poorest of White people in 1865, 1900 or 1965 considers a black person their equal. While every TV commercial features blacks today and interracial relationships are en vogue today, even when I grew up that was considered verboten. Not so long ago. Another thing was those descendants of the planter class were still running things because that was just the social order in small Southern towns (and I am from a fairly liberal Southern town.)
I get it everyone hates slavery, White supremacists are horrible. But the old social order didn't start breaking down until poor Whites like me got university educations funded in main part by fighting this country's wars. There is a reason reconstruction worked out like it did, the people at the time on the ground knew what would work.
