It is obvious to anyone who looks at the situation objectively that Blacks in the USA and in Africa are less intelligent than Caucasians. They are not only stupid, they are extremely violent.
Blacks in the USA are overly dependent on welfare and Blacks in Africa depend on foreign aid. They incapable of taking care of themselves and therefore are an undo burden on society. Blacks are a classic example of stunted evolution. While technically they belong to the human race; realistically they are are sub-species. Based on their abilities and behavior I would call them Africanus Criminalus.
