True, but the fact that they were addressing the issue shows that the ambiguity is there. Here is an extract from an article about the Bantu minority in Somalia (a country with close ethnic ties to Ethiopia). The link provided gives access to the full article.

"The Bantu people's predominant Negroid physical features are distinct from those of the Somali nomads and give them a unique identity. Among the physical features used to differentiate the nomads from the Bantu is hair texture—jareer (kinky hair) for the Bantu people, and jilec (soft hair) for the non-Bantu. People with such features are subjected to a variety of discriminatory practices. They are often excluded from political, economic, and educational advancement. The Bantu, therefore, have had to settle for the lowest and most undignified occupations."
