The first slave owner in the colonies was Anthony Johnson who who was black. Furthermore, there were a significant number of free blacks who owned slaves in the US right up until the civil war. There is even a Wikipedia article on black slave owners:

Furthermore, almost all African Americans today who trace their ancestry to the slaves are of mixed race.

If you take the totality of the above, reparations are completely insane for the following additional reasons (there are already many well known other reasons I won't repeat):

1. Are mixed race black Americans (which is almost all of them) going to have their white part pay reparations to their black part?
2. Is it going to be acceptable, given the stated stated intent of reparations (obviously not the true one), that reparations are going to be paid to ancestors of slave owners if we take the black slave owners into account? We'd basically be rewarding people for having owned slaves.
