Screw yew.
Blacks sold other Blacks to the Arab slave traders who sold to European and USA slave traders who sold them to various plantation owners in USA and other Countries.
So agreed, the Blacks of Africa need to pay reparations first to the Blacks they sold to be slaves. The Arabs need pay, especially since they own slaves to this day. etc etc
And when the above two Peoples have paid, then we can see if the Europeans involved owe.
For USA Blacks, cost of upkeep and support (such as 150 plus years of welfare payments and related) need be deducted from the reparations....which considering the number of Blacks still taking from the Public trough, means the USA Blacks owe big time.
there...done.
