Who counts, i.e, functions as a white person?   "Asians," "Arabs," "Hispanics," "Persians,"  etc.----sometimes and some places?  As in physics, there is an uncertainty principle about the momentum and position of fundamental elements of the system---white people.

What is the difference between a black person, a nonwhite person, and a white person? 

Suggestions are discussed to move the science of counter-racism forward.
