Have you considered the fact that whites discriminating against blacks is commonplace in the United States (as well as many other countries) while accounts of whites feeling discriminated against by people of color is much more rare?
Which makes sense, because whites constitute 60+% whereas blacks constitute 13%. Even if everything in the world was exactly equal, including percent of racist whites and blacks, blacks(or really, the group with fewer members) would experience more racism because of the disparity in population numbers.
