For anyone who might have missed this in English or Language Arts class in high school, the main subject of the original post is the opinion that ancestry related to slavery—whether as a slave or a slaveholder—is insignificant and should be treated as little more than a trivial detail, perhaps worth mentioning in casual conversation but not deserving of much importance.
The main subject of the OP is Ms. Rael's opinion that
"Finally, this whole business about whether someone had ancestors who were a slave or slaveholder is just ridiculous. It means nothing, other than a mildly curious footnote in someone's ancestry that might make for interesting cocktail party conversation. But that's it."
is equivalent to "RACISM SOLVED on IIDB!", because reasons -- reasons perhaps having to do with what she missed in English or Language Arts class in high school, or perhaps having to do with parasitic memes she swallowed hook, line and sinker. Thebeave did not imply racism was solved. Thebeave did not even imply ancestry related to slavery—whether as a slave or a slaveholder—is insignificant. You appear to have committed a Hasty Generalization fallacy and imputed the results to him. The "someone" part of his statement that you deleted in your attempt at paraphrase
matters. He was talking about its meaninglessness
on an individual basis.
He was right. It has no importance
on an individual basis. Harris has slaveowner ancestors. So what?
Everyone has slaveowner ancestors. Harris has slave ancestors. So what?
Everyone has slave ancestors. People have been enslaving one another for millennia and there's no more chance of finding someone to breed with who has no slaves or slaveowners in his or her ancestry than someone who isn't descended from a thief. Heck, half the people in the world are probably descended just from one or another of the slave-girls Genghis Khan owned and impregnated. So what? Most people were slaves in a lot of Western Europe in the Middle Ages and more recently than that in Eastern Europe. Enslaving Slavs was so common our languages named the institution after them. So what? Who cares if some Russian-American's ancestors weren't freed until 1861?
But that says nothing one way or the other about
collective ancestry related to slavery. The fact that two hundred years ago most of the ancestors of most American black people were slaves, and most of the ancestors of most American white people were free, is important for all sorts of reasons having nothing to do with cocktail conversation. The circumstance that some Hawaiian guy happens to be descended from a slaveowner through his white mother and from a lot of free Kenyans through his black father is insignificant. The circumstance that his choice of parents left him
looking like millions of American black people most of whose ancestors were slaves two hundred years ago even though his own ancestors weren't, and consequently he got treated
as though most of his ancestors were slaves back then, is very significant indeed and has had major effects on American society.
And thebeave did not claim otherwise. Collective ancestry is not the same thing as individual ancestry.
