Right, black people do look different. Is that your point? Are you saying that they are evolutionarily inferior?  I believe he is pointing out that race is much more than just skin colour. A racially Black person could bleach their skin, dye their hair platinum blonde and wear blue contacts but you could still tell that they are not Caucasian just by looking. Inferiority really has nothing to do with it, fact is, we're biologically distinct and wish to keep it that way.
