The central claim in Rodriguez's <em>“Blaxicans” and Other Reinvented Americans</em> is that the separation between white and black Americans is no longer the identity people use nowadays. Culture is not a static thing but a fluid one, and is changing constantly, individually and collectively. People are choosing other characteristics to identify themselves with and form communities.
With this final statement , Rodriguez is claiming that he has lived in a Chinese neighborhood for so long that he has acquired several aspects of that culture. Despite being "Hispanic", ethnically speaking, he doesn't have much in common with that culture, simply because it doesn't exist: people in Latin America don't identify themselves as "Hispanic", it was just a word created by the government to classify people. If it has ever worked as an identity people used to describe themselves, that use is decreasing nowadays.
