Tom, you seem to be saying that Census data today are unreliable because people self-identify.  Indeed, transgender men and women today are choosing to identify as the opposite gender from what their anatomy clearly displays, and teenagers with man-anatomy now call themselves girls and demand to take showers with the girls at school.  You seem to be saying that a lot of those 600,000 people who self-identify as ethnic Hawaiian are actually transracial people with no native blood.  How interesting!  Facts no longer matter.  We can make things up as we go along.
