If racism = prejudice + power then may still be possible for a local maxima of power to exist. When a bunch of black power advocates beat a white person because nobody is around to stop them, they clearly show that they are the local maxima of power. Even if "systemic oppression" occurs as a global maxima, there is certainly a lot of variability of who's in power in the rest of the graph.
