Even if you actually were looking at maladies, does the phrase “cure worse than the disease” hold any meaning for you?
Besides, who needs White when Celtic, Germanic, Slavic, Iberian, Gallic, etc. are all perfectly viable descriptors? Main reason we have generalized “Black” is that slavers had no care whatsoever as to which parts of Africa their prisoners came from. It’s the best we have to work with besides the lengthier “African-American”.
