Something else ... We dissolved the Empire (Empires) too early in Africa and the place has gone to hell in a hand-cart because of the tribal nature of some countries ! Exceptions being Botswana Zambia and Tanzania.
The collapse of family, caused by the Marxist death cult, did the damage to the Afro American community. Watch also how the Latin American culture of political violence has started to seep into the US along with Islamist violence and political corruption.
I think it's their mentality and lack of intra-personal abilities. They do not want peace or to assimilate. They want payback loaded with their racist and political hate for Whites. They generally have conception problems and have a false sense of ability and grandeur. If they got proper schooling and dropped their ego filled inferiority complex expressed in their hate and crying toward the system and got on board we all might get along a little better. All that I see these days is that it is not Whites keeping racism and hate and violence alive.
Introverts are less likely drawn into social conflicts, and pushing them. Europeans who live inside because of cooler climates fit introversion
Extroverts are more personal about how they fit into society scene, thus fearful of being demoted by someone. Africans who live in topical climates are more likely involved socially because of the open air social scene.
As for living in America, genetics probably have internalized these traits
What can be implied from the fact that African-American homicide rate mirrors African nations while European-American homicide rate is comparable to European nations?
"Implication" is neither "deduction" nor "induction" nor "conclusion.
As such, one's implications is more a result of personal bias than objective truth... as evidenced by a poll with only one definite choice.
