I assume your post was mostly tongue-in-cheek, as I mostly found it funny.
Although I think everyone here agrees that broad based reparations are a joke, I think if someone has evidence of an actual claim that their ancestor were cheated out of because of their slave status, the descendant should get reparations as a successor in interest. For example, if there was a land grant by a master in his will but when the slave went to claim it, the grant was disallowed and the land went to another person. I think that narrow situation is fair basis to receive some sort of reparations for the decedant of the slave.
As for the lives lost in the Civil War and reparations for that 1) their ancestors brought the slaves here, so they created the situation 2) the war didn't begin as a quest to end slavery and 3) although the slaves for the most part were grateful for their freedom, they didn't ask anyone to lay down their lives for their freedom. It was a charitable act by good men. You shouldn't cheapen it by asking to be paid at the end of it.
My post was entirely tongue-in-cheek to ridicule the entire idea; I would agree that specific injustices should be dealt with, but it would seem impossible by this time.
