Worse, is its affect on us--it makes us less empathetic to each other and this is a major problem. This is the reason why we act like crabs-in-a-barrel. And this lack of empathy reinforces our imposed racial inferiority.
White supremacy has institutionalized the Western worldview, which encapsulates its views and conceptions of life, science, humanity, culture, everything. It reinforces black inferiority just because it is the logical and inevitable corollary to white supremacy. So, in Western civilization you can never escape the propaganda of black inferiority. It's in the language: Look up the definition of the word black in the dictionary. Look up the word denigrate--it means to ruin or worsen by blackening. (What happen to strengthening by blackening?)
Cleverly embedded in many of the fields of study that developed during Western ascendancy is a white supremacist foundation or assumption. Science serving racism, is called scientific racism and it has poisoned and even given birth to a number of disciplines, including but not limited to anthropology, evolutionary theory, Darwinism, Egyptology, anthropometry, and craniometry. To be educated in the West is to be exposed to white supremacy; to be entertained in the West is to be exposed to white supremacy, again, it is very difficult to do anything in the West and not be expose to white supremacy. And while white supremacy has glorified anything white, it has castigated all thing non-white, and especially things black.
