No, I'm sure that slavery isn't making a comeback, but please understand that you're asking someone (me) who is adamantly opposed to slavery. I believe slavery was evil and that slaveholders were very sick, dependent puppies who were in need of some tough love to free them from their addictive, indolent lifestyles. Lincoln gave them that tough love and, as a result, many slaveholders went on to live productive, self-sufficient lives.
And, they (the slaveholders) had said that it couldn't be done. They were saved in spite of themselves!
