  Humans are ONE kind. Eagles and pigeons are two different kinds. Eagles eat pigeons. If a person eats another person, it's called CANNIBALISM, the eating of your own kind. All humans are Homo sapiens or Homo sapiens sapiens.  Different races are like different species of the same overall species which of course would be human, just as lions and tigers are different sub species of the big cat family. Lions and tigers can reproduce purrrfectly(get it...yeah...they're cats) healthy offspring it's called a liger.....just like Whites and Blacks.....but they won't do this in nature, you have to force them to breed together, in a natural setting a lion and tiger will not breed together because they know better. Human beings these days are being taught and forced to deny one of the most base instincts of all living creatures........racism, or racialism if you prefer, it sounds much more PC. Do you honestly mean to tell me there is no difference between the races?? Only skin colour.....riiight.;) You must be pretty brainwashed or naive to believe that horse crap.....
