It sound like these people walked away more educated about their history, which is what the LW's family would be. But you're saying to leave the past past.
I think that's YOUR take, but others would find it to be a burden. Especially finding out their ancestors had owned slaves.
I saw a documentary on the descendents of the largest family of slave owners in U.S. history. The women took it harder than the men. Then they were given a tour of the slave quarters in the Caribbean (slaves were held in the Caribbean until prices in the U.S. were at a certain minimum, meanwhile they were put to work growing sugar cane and making rum, which then was used to buy more slaves in Africa).
THat's where the men changed their tune, from "This has nothing to do with me, I didn't do any of these things to slaves from Africa," and "It was how the times were, I'm not going to judge my great-great-great grandfather for doing something he didn't even realize was wrong," to "Wow, my ancestors had to know this was evil." From one tour of the slave quarters.
It. was. Fascinating.
