it is the American. the children of the world combining with each other to produce children of different heritage and race and then those children combining again. it is the fundamental "melting pot" of America. from the many races come uncounted different combination's and so a greater race that is not single but multiple and varied and expressed as "American".
is the typical American of a single race? probably not. technically i'm german and english and so of two different races. a girl i went to high school with was of lithuanian and some other west european descent; technically of two different races. then there is president obama, half african and half white, though his mother could be the result of any number of "races", i don't know.
the american "race", if you can call it that, is superior in the world because it is a vast combination of all possibilities of all races from all places.
in the classic sense of the word "race" we are not one, we are many and in many combinations. yet we stand out above the world precisely because of that.
there is no "master race". hitler was totally wrong and in every conceivable way. and yet there is the American. not technically a race but the best of blends of all.
later.
