The second half of the 20th century was marked by decolonization in Africa. New flags and anthems replaced colonial ones albeit after bloody wars in some cases, new names replaced colonial ones: Gold Coast became Ghana, Upper Volta became Burkina Faso, Northern and Southern Rhodesia became Zambia and Zimbabwe respectively, etc. Presidents and prime ministers replaced governors. The principal idea behind all these changes was to reclaim African pre-colonial glory.
The first half of the 21st century should be devoted to the decolonization of epithets (terms of abuse) or distortions introduced before or during colonial days. These epithets were deliberately coined and have been repeatedly applied since then to the present day in 2010 to keep down Bantu people (as opposed to Bantu-speaking Nilotic people). You still hear some Bahima and Bahororo boasting that any one of them is worth 1000 Bairu, others are telling us with confidence that their women are more beautiful than Bairu women. Ms Kesaasi confirmed this in April 2010! To repeat, these epithets are intentionally used to devalue Bantu people irrespective of their education, work experience and even wealth.
