Can White identity exist without non-White identity?

Ponder this:

White identity cannot, would not have, and will not exist without the existence of non-White identity. So what does that say about being White? That being white is less about being something, and more about not being something else. What is that something else?

What do we give those who are considered "non-White"? Well, ethnic identity, for one. We call them Hispanic-American, Asian-American, African-American, etc. We attribute different types of music to them. If a White man goes to an Asian restaurant, there is a consensus that he's eating "ethnic food", in contrast to "normal food" (of course, such as Hamburgers, hot dogs, sandwiches, etc.)

We give them "foreign language". Hispanics are tied to Spanish, Asians to a multitude of languages, etc.

We give them 'other-worldly' attributes, such as "natural dancers" (black people), "great at math and science, breed like rabbits" (Asians), etc.

It seems that everything that has to do with being non-White is about having ethnicity or culture. Being white is defined by it's neutrality. One is 'normal', a 'person', an 'individual'. One can judged as such, as evidenced by the 100 or so Supreme Court justices before Sotomayor whose personal experiences didn't call into question their impartiality. You can miss a basketball shot and not have it reflected on you that there's something not normal about you. You can show up late for class and not have being lazy ascribed to your tardiness, as well as your racial behavioral characteristics.

Being race-neutral, the "norm", the benchmark means that you are what everyone else is judged off of. Obama being called "race transcendent" did not mean he did what other Presidents did. It means he rose above being black. John McCain never transcended being white, nor will he ever be asked to. This is a privilege, to be considered the norm so as to never have to "overcome" a racial status.

In essence, being a white-American (and in many ways, a white-American male) means more in what you are not rather than what you are. Blacks, Asians, Hispanics - THEY have a race and a racial identity. Whites are just people. It means not having to conform to anything outside of a comfort zone. It means being given the benefit of the doubt, being judged as an individual.

Without Blacks, Asians, Hispanics, or any other group, White would not exist. There would be nothing for it to exist in contrast to. There would again be Irish, Dutch, Spanish, French, Swiss, Polish, Germans, or any other European ethnic group. Asians do not call themselves yellow or identify themselves with others of East Asian heritage unless they live in a White centric society, like America. This is just as Europeans did not identify as such until their arrival into the New World and the creation of it's power structure.

Knowing all of this, what does it say about those who choose to self identify, consciously or subconsciously, with the term "White-American"?
