Particularly the "Black Republics" where the CSA dumped a lot of its Black rioters and other rebels. They rounded up Blacks in the areas with the highest crime rates and dumped them there. Officially they are independent but they are as dependent on handouts from the CSA government as the late 19th and early 20th century Indian Reservations.
It's a little complicated -- a lot of the CSA "states proper" are either essentially governed by the newly liberated coloreds, or are have fairly stable political alliances between the "black parties" and forward thinking "white" parties (that are actually interracial); these states are represented in the Congress along with some more holdout white supremacist states, who themselves have tried to contain the "nigger problem" by rounding up the more "uppity" of their citizens; the CSA feds, mostly controlled by moderates, said these places that were meant as internment camps have quasi-sovereignty "the same as the states" (but without representation in Richmond), and are getting aid passed out by the CSA, but collected primarily from the "exiling states".
So now you've got a situation the white supremacists are calling "extortion", the hardline black leaders (and many not so hardline) are calling "slow genocide", and the moderates admit can't last. Which really only enforces my original point that the US
does not need to wade into this crap.
OOC: Since the Blacks just got out of peonage I assume they are about as well treated as Blacks were in the South during the 1950s.
OOC: I guess it depends on what we mean by "just" -- also, depending on how they came about, the "reforms" could have seen a progress more accelerated than OTL
