You know its not that they are least intelligent some people also, even whites people tend to have least intelligent its by nature my friend white or black they caught up on the nature of their homes or land even their country but still this what i have observe that black people are the strongest in sports also so they are intelligent back when they are being slave they really are not that superior i mean they are just rats to the white and the whites are thinking that black are least intelligent and they are just slaves and rats for all but now black are really showing good things i mean great things to be exact because they are the strongest in sports so they are intelligent as a for the other countries well blacks are living by them self and tend to be with nature so they are intelligent to live that long so in that "WE ARE EQUAL AS ONE HUMAN BEING BUT WE DON'T SHARE OTHERS NATURE THAT'S WHY PEOPLE JUDGE " that's what in my observation have a good day to you and good luck
