Don’t confuse cultural effects with race. Just because a majority of people living in a specific culture are of a particular race, does not make the resulting behavior genetic.
The *only* way you could claim that the behavior is a result of genetics (specific to that race) is if you could compare two different racial groups who have exactly the same culture and document differences in behavior that cannot be explained by any other cause.
The Vikings used to be brutes who caused fear wherever they went, because of their little habit of stealing, raping, murdering, and burning everything they couldn’t take with them. Yet here I am, married to a descendent of Vikings...and I am not at all afraid, nor have I ever seen him engage in those Viking behaviors. And I have never met a Norwegian who did not act civilized.
I can assure you that there are more violent whites in my mixed neighborhood than violent blacks (our next door neighbor has issues). And last I checked, the violent Islamists are still white.
Genetics is not destiny, but culture is.
Don’t confuse my observation as implying that there are no other populations who have the genetic propensity for violence. There are others, certainly. But, any study of sub-Saharan Africa and the conduct of its population after migration will support this thesis. Its just an inconvenient truth.
PS: sorry about your neighborhood. But, with 13% of the population, young male blacks committing 54% of the violent crimes cannot be ignored. Is it any wonder that no progress has been made by the billions of dollars wasted on cultural remedies?
