Well my question did indeed create a healthy debate, I now feel obligated to publish my controversial theory, as a thank you to all the contributers to this subject, especially sp1814 who being in his own admission a black person, and who may be the one most offended by my theory. I do hope not because as I stated in my question I am not a racist, I just want to put a new slant on this subject.
As with the recent debate regarding savage breeds of dogs. It got me thinking that could it be that humans also have different aggresive traits, along with other differences that exist in the genes of the various races on this planet. For example, Why are Males more aggressive than Females? Why do Asians tend to be the most intelligent? Why are Europeans generally the most placid? Why are Latins more fiery? Why are Blacks better athletes, boxers and yet do not achieve at swimming?
Having thought more deeply into why it seems Blacks tend to be more violent, I decided to surf the web on this subject and came up with a book called Race,Evolution, and Behavior, written by J. Philippe Rushton of the Department of Psychology, at the Universary of Western Ontario, Canada.
So before anyone jumps in to call my theory racist rat trap, please take the time to read some of this book, especially page 9 on diffences among Blacks,Whites and Orientals and pages 14-15 on crime.
