In Angola however, black Africans never made up less than 95% of the population, so the demographic situation there (and in the other Portuguese colonies) was never the same as it was in Brazil.  Furthermore, the claim that racial mixing equates to racial egalitarianism is problematic, as there are significant racial inequities in Brazil and other countries with large mestiço populations.  The fact that the Portuguese were leaders in international trade of African slaves for nearly 400 years also challenges the theory.
