There's a case to be made that "Blacks" got their "reparations" paid in blood during the years of 1861-1865 on the battlefields of Bull Run, Gettysburg, Shiloh, Antietam, and scores of other battlegrounds which ended slavery in the USA via the War Between the States with a Union victory over the Confederacy.
Possibly a mixed blessing since many went from having food, shelter, clothing, etc. provided in exchange for work; to having to fend for themselves to acquire the basics of living~surviving. FWIW, there wasn't any real "social safety net" for anyone of any race or ethnic back then.
Claims for "reparations" for how ever reason after 1865 will require some forms of proof of the disenfranchisement as well as proof, DNA ancestry?, that one is descended from former slaves and not from Freed Blacks prior to the WBS/Civil War.
Also, the issue of reparations might need to be expanded to other/all races and ethnics as well since at various times and places some could claim similar post 1865 disenfranchisement.
Japanese-Americans living on the West Coast USA in 1942, and their descendants, might have the most valid claim for reparations since so many lost their personal belongings, homes, and businesses when gathered and sent to internment camps during World War Two.
And there remains an issue of how much do "sons inherit the sins of their fathers (or grandfathers)" ???
Are those of Irish and Italian ancestry also owed "reparations" for the discrimination's and/or disenfranchisement's their fore-bearers experienced when immigrant to this nation?
