What is an Hawaiian? Is it someone with 100% Polynesian-Hawaiian blood?  Is it someone with 1/512th blood quantum blood? And, you sovereignty fringers don't cloud the issue with that identity stuff. You know, it's not how much you are of something , it is who you "identify" with.
Really, if you are 1/512th Polynesian-Hawaiian, does that really qualify you as a "Native Hawaiian".
If I am just 1/512th Japanese, and the rest Scottish and Greek, does that make me Japanese?
So, without really knowing how much of the desired blood quantum is considered enough, (the U.S. Government has ruled 50% or better), these stats are simply nonsense. 
I read that by the year 2250 there will be NO more "races" do to intermarriage.  I can't wait!
