Essentially, this white devil is saying that black people are naturally more aggressive than whites.
The entirety of American history has proven that to be false. Black people were known as being 'meek, humble, shuck and jive fools' up until our liberation in 1865. Then, the rhetoric of white people became that we were violent criminals.
American history proves that white people are the most aggressive, evil beings who have inhabited the United States. The current condition of the red man and the black man are proof of this.
