You tried to tell me how reparations "works", and when I asked you to give me ONE real example of your proposed system in action you start doing the coli-smilie shuffle. That says all I need to know right there.
Nicca what
The white mama Of the biracial person family owned slaves and took advantage of programs and loans that blacks couldn’t access
the black dad of the biracial person descends from slaves
what examples of reparations have YOU seen where this person would be treated like a bonafide black person
The truth is reparations payments to *individuals* as far as I know has only happened based on those that were directly victimized, their spouses, or direct heirs, not their descendants.
Descendants have only received reparations through lump sums paid to organized self governing nation-groups like Native American tribal governments. And yes there are many members of said nations who are of mixed NA white parentage and they benefit from the payments to their nation just as much as the next member.
And FYI there were approximately 700 Japanese internees of mixed (mostly white)hertiage as well. They would be just as eligible for reparations payments as a full japanese internee.
So, in reality your proposed system tallying grandparents of a certain ethnicty to determine the amount a person should be paid in reparations has no historical precedent, and is just something you arbitrarily came up with. So, in that case you'll have to argue it based on it's merit alone and not try to act as some kind of authority as if this is the established "rule" on how reparations payments work, because it isn't.
