Under my philosophy, a person can't be bad just for his skin color. What makes a person bad or inferior compared to other, is it's cultural level/type, education, traditions, idiosincracy, critical thinking, use of logic, common sense. Now if we analize, we can find a lack of these components usually, and unfortunatelly related to some races and/or country of origin. Now can we say that those races having a lack of these components have less capacity or an "inferior" brain? NO. The cause of this is a) segregation and discrimination forcing them to stay for generations away from a good education b) victim of an dictatorial/abusive/socialist system on it's country of origin. Based on this I repeat that there is no intelectual differences between races. They all have the same capacity and abilities.
