Blacks are simply inherently violent. Their violent nature is the direct result of an African evolutionary strategy that has no place in the modern world.
Europeans evolved with a different strategy, one of kindness and cooperation.
Strange, I lived for three years in West Africa in a place where violence was rare (Ghana), certainly a place far less violent then, say, Working Class Northern England where I grew up.
Must be them Ghanaians on the one hand, and them yobs on the other, were practicing a different evolutionary strategy.
