The Negroes of Equatorial Africa were mainly ethno centric..
Latin America for the most part is relatively stable but definitely multiracial.
But both of these people groups contributed but little to human progress and civilization.
Generally ,few know how to judge other racial groupings. Relying on skin color alone is seldom
the answer. The only effective way to prove the worth of any race is by the sum total its accomplishments over a long period of time. .
You can't rely on form of government or cultural values alone in any event .Given that there are many Negro tribesmen who in fact enjoy a greater and more effective form of government than many nations in the west live under.
It's all about the sum total of accomplishments that remains the standard by which any race of people can be judged.
