Is “expanding definition of whiteness” a real thing?

[Bismarck]

I think the focus on the word “whiteness” misses the point. It’s more about who is considered in the mainstream of American society, and that has definitely expanded. Asians and Hispanics will fall into this eventually as long as the democrats aren’t successful with their racial balkanization project. It’s isn’t that Vietnamese or Mexican people will stop being Mexican or korean, but that it won’t be a meaningful category that excludes people from the mainstream. Plus most people with Asian or Hispanic ancestry in the future will also have non Hispanic white ancestry. Just like with Italians or polish or Irish intermarriage will lessen the separateness of these groups.
