"White" in the US Census means someone who ticked the "White" box on the census form. A "White Hispanic" is someone who chooses to tick both the "White" box and the "Hispanic" box. Anyone can tick any box they like, out of the boxes available (and if they don't agree with the choice of boxes, they can write in whatever they like, and the Census Bureau will make its best effort to shoehorn their written response into its categories, or just put them in the "Other" bucket if it can't work it out). If they don't view themselves as "White", why are they putting themselves down as that on the Census?
> 90%+ of all U.S. Hispanics feel like they are part of a white majority?
I feel very hesitant in speculating about the feelings of tens of millions of people whom I don't know–and who of course are not all going to think or feel the same way, but who are going to have a very diverse range of feelings and opinions. Rather than speculating about their feelings, why not just go by what they voluntarily choose to put on their US Census forms?
> The vast majority of Hispanics in it fully realize and are made to feel like they are part of a minority in the U.S.
There are white minorities, so identifying as "white" doesn't necessarily make white-identified Hispanics non-minority. If an (ethnic majority) German or Russian or Finn moves to New York City, they are going to be an immigrant minority in their new home, but they and everyone else will see them as "white". A European-descended person who moves to New York City from Buenos Aires has Spanish as their native language instead of German or Russian or Finnish, but why would their experience be fundamentally different? The Spanish-speaking immigrant will be officially classified as "Hispanic", the German/Russian/Finnish-speaking immigrants wouldn't be, but they are all equally white ethnic minorities.
