I have a question. Have you ever reached out to or been contacted by a DNA match who is connected to you because of slavery? This came up on a Facebook forum. One African descendant contacted her match who was of European descendant and was rebuffed.
Through the years I have contacted a few genealogy hobbyists who were related to me and/or related to the slave holder of my ancestor. I have seldom had any issues from the contact. But I am not quick to reach out to those descendants who just may have clues to the lives of my ancestors held in captivity. It's a personal choice.
I also wonder how those European descendants feel when they find that they have relatives whose DNA is mostly sub Saharan African. Most of my DNA matches are not the same color as I am. Even though I am 71% African, the majority of my matches come from my 26% Irish/Great Britain relatives. They have not reached out to me either. I assume it's because I have little to add to their search. I have been heartened, though, by some who have included my family on their data base.
I understand from what I see on genealogy television shows that many are appalled to find out that their ancestors were slave holders. I think the more egregious fact is that we are related because of institutional rape. That is a far worse thing to get your head around.
