Blacks make up about 13 percent of the population, yet manage to commit half the murders. They also manage to do 80 percent of all interracial violent crime - meaning that, per capita, they commit violence on other races at a rate twenty (20) times more often than non-blacks do. Collectively, they are an incredibly violent and dangerous people.
It’s even worse than that, because about half that 13% would be females, and others would be children or elderly, right? What percentage of the population are black males in their teens and twenties? Because they’re doing most of it.
Part of the reasons for their failure to thrive as a continent. What has come out of Africa without western influence? What have they invented. No written language, no math, no science, no agriculture, nothing.
