Whenever I study history, I cannot help but notice how many people Europeans have killed. I think millions of natives in America and Australia, hundreds of thousands of Indian and African slaves. So, I think this is completely untrue that black people are violent. Even, Muslim aggression has no match. Indians are known for being violent towards women. So, these types of generalizations based on race are totally bogus.
There are many factors that contribute to a tendency toward violence. Upbringing, societal conditioning, mental illness and even values all play significant roles in a tendency to be violent. This is also why violent people exist among all races. If one group of people appears to statistically be more inclined toward violence, chances are that one of the previously mentioned factors is significantly impacting those numbers.
There is no way to create a deciding factor regarding what race is more violent than any other. Whether people are of one race or another does not impact what way people act when they are engaged in dangerous or violent activities. All humans are equally inclined to aggresive behavior, but these different interactive outcomes are dictated by many factors outside the realm of genetic dictation. The total outcome of how people act in violent situations has little to do with race and more to do with upbringing and social economics.
Violence has been shown across all races since the beginning of the written word. Various cultures have stories of battles, wars, weaponry and conquest over other individuals and groups; it is not just black cultures that have exhibited violence towards other parties. Violence may be due to economic circumstances, however. Statistics may be skewed showing that black people are more violent because there is a higher concentration of black people in poorer communities, where more people have to steal to survive.
Around the world, one constant is that where there is poverty, there is violence. People who are close to the edge feel like they have little choice in how they survive. In the United States, blacks as a group are in the lower class of wage earners, leading to more desperate situations and violence. So blacks are not more violent, but their positions are often more desperate.
