I see all of this with a bit of nuance. The U.S. government was the primary perpetrator of these actions and the lands/properties in question are identifiable and quantifiable.
There is no doubt that black people were enslaved and treated as chattel, but most of these actions were taken by individuals who profited on the backs of their free labor. I would be on-board with civil suits being drawn where descendants of slaves could draw lines between them and their slave owners to become claims for reparations. I'm also not opposed to much of the affirmative action rules that were in place to level the playing field given the systemic inequalities that are ingrained in many of today's socials constructs.
