Your right, we should continue to legally segregate because it is too inconvenient. Selfish.
No, we should have a phased in plan.
How can you even begin to make this argument? What is wrong with you? So, you believe they are better off enslaved? Interestingly, the plantation owners made this very argument. "So what if we whip them, rape the women, and hang them if they act out. At least they have a job, right?"
Of course they should have been freed... but it should have been done in a phased in approach that compensated the slaves for their work and abuse and compensated the slave owners for loss of property.
Instead, the bullying of the north caused the south to secede... which caused a war in which 98.7% of southerners who DID NOT OWN slaves were forced to fight and die for. In the end it was reasonable to expect the non-slave owning southerners to blame the deaths of their family members during the war on the former slaves. (even though it is wrong... vilifying the weak is just human nature sometimes)
In the end, we should have phased in strict laws on how slave owners should treat their slaves... ban the importation of any more slaves.. enacted a program to purchase the slaves and educate them and provide them with a piece of land on which to subsistence farm, if they wanted it. Until there were no slaves left.
If we had done it right, the former slaves would have not been easy pickings for the former slave holders to terrorize and abuse.
