And I honestly fail to see the distinction you're making: you insist that financial obligations are different because, to paraphrase: "there's a paper trail and defaulting is bad". But slavery and its legacies also has a paper trail, likewise with human life and misery, and not resolving this is also bad. You have yet to provide an argument that fundamentally CANNOT also be applied to reparations: you've only given arguments over how we merely don't apply them to reparations. This kind of definition game, that 'reparations aren't considered that way because we don't consider them that way', reminds me of when there's outrage over police murdering someone and people insisting it's not murder because murder is an unlawful killing.
So, I ask you, without resorting to mere definition, what is the difference between "People make moral choices; you are trying to saddle people who didn't make those choices with some sort of culpability" (reparations) and "People make financial choices; you are trying to saddle people who didn't make those choices with some sort of culpability" (debt)?
