All this assumes that “white” is a single “race.” In reality, it is a broad umbrella covering a variety of ethnic groups. What would I — a first-generation Russian immigrant — have to celebrate in common with descendants of Spanish, Belgian, or South African immigrants? Our cultures and histories have little overlap. Frequently, we don’t even have the same skin tone! The only thing we unambiguously share is a racially dominant position in society, which is not something I want to revel in.

An interesting tidbit from Wikipedia:

> Description of populations as "White" in reference to their skin color is occasionally found in Greco-Roman ethnography and other ancient or medieval sources, but these societies did not have any notion of a White race or pan-European identity. The term "White race" or "White people", defined by their light skin among other physical characteristics, entered the major European languages in the later seventeenth century, when the concept of a "unified White" achieved greater acceptance in Europe, in the context of racialized slavery and social status in the European colonies. Scholarship on race distinguishes the modern concept from pre-modern descriptions, which focused on physical complexion rather than the idea of race. Prior to the modern era, no European peoples regarded themselves as "White"; instead they defined their identity in terms of their religion, ancestry, ethnicity, or nationality. Contemporary anthropologists and other scientists, while recognizing the reality of biological variation between different human populations, regard the concept of a unified, distinguishable "White race" as a social construct with no scientific basis.
