Why does living next to someone else destroy an ethnic identity? Does a chinese family moving into an italian neighborhood all of a sudden mean that no one can open an italian restaurant?

Does a Russian family moving in next door mean that I have to start drinking Vodka instead of…
>Does a chinese family moving into an italian neighborhood all of a sudden mean that no one can open an italian restaurant?

If this was actually about 'culture', we'd have a different discussion here. Nothing prevents a chinese/italian family from making dumplings and home-curing some pancetta. If anything that seems like a pasta/noodle dream-team of family. The cultural elements that make up an ethnic identity are remixed over time, and the ones that work tend to stick around.
Is there some creative destruction that happens there? Sure. But that's the norm, not the exception. Plenty of great stuff comes out of it. We wouldn't have chicago-style deep-dish if all the italians had to stay in Italy and use fior di latte and mozzarella di bufala exclusively.
