If infact that "survival of the fittest" is true, then what does it mean to be fittest and why are they fittest? are they fittest because they survived or did the survive because they were fittest? and please do not cling to the darwinsm claim of natural selection which ultimately does continue to call into the category of tautomology. because he infact just changed his words with the same underkying belief.

Now that "All races are equal" statement is nice, but then, we also have the theory of adaptive evolution.

Is there a "smarter race" or is it too early to decide on that?
