Did you seriously just compare plantations to the Holocaust?
I used Gettysburg and Dachau as examples of places where terrible things are known to have happened, that are now tourist attractions. They are solemn memorials, respectful to history and the people that suffered there.
I am suggesting that plantations in the south should be that way, instead of just celebrations of fine imported silks and architecture.
If I ever buy one, that is how I would run it. A lesson in real history (including the grandeur and the horror).
The people who own them can do what they want of course.
Just saying it seems awkward to stand on a tour all about what kind of fabric and wood there is in the house, while right outside the window a race of people were enslaved.
