Why men? Well I think its pretty obvious. Men are genetically more aggressive, and genetically much more prone to commit violent acts. Does saying this mean I am sexist and hate men? No, it's just an obvious observation from the data. An observation does not imply anything more.
Ok, so why black people? This is where people's brains start freezing up from social conditioning. Nobody will let themselves analyse this in a logical manner, even though the data shows the exact same pattern and rationally the same factors should apply. You will only ever get name calling, knee-jerk responses and purely emotional, speculative arguments here.
I encourage you to look at the data you yourself have posted and to draw your own conclusions.
