Black persecution under US race systems is historically unique.

Evidence

Another common question is: Why should reparations be limited to black Americans? Aren’t other groups equally deserving? Short answer: The history described in Part II is sui generis. No other group has experienced that level of sustained persecution because of their race as black people have—except perhaps for Tribal Nations, which have received some form of reparations. Insufficient yes, but at least something. The longer answer is, if you are thinking that poor white people should receive reparations, recall that they have not been targeted for exclusion from any of these systems of oppression because they were white. — Dorothy A. Brown, Getting to Reparations, 548

• QUESTION: The concession that Tribal Nations ‘have received some form of reparations’ invites a comparative question: what did tribes get, and does that weaken the sui generis claim or the case that nothing short of reparations works?
