This isn't a very productive discussion, we could both be imagining entirely different cities and situations. I live in Australia, so I can't speak for American cities. The diversity in cuisine here comes from our now decades of immigration policies, people tend to immigrate for study or work, both of those things concentrate in cities, voila you have massive mixed communities serving mixed cuisines to that now multi-generational mixed community.
Your comments and thought process is racist as fuck.
Do BIPOC not enjoy “ethnic food”? Do you not have any BIPOC friends? These “daft white person” you converse with what’s their educational background look like?
Immigrants usually don't leave their homelands to move to a foreign country to eat the food. Usually they do it to improve their financial lives. They probably enjoy it, but if you ask them "why did you move to Atlanta from Mogadishu" the restaurants probably won't be at the top of the list like it is for snotty white people.
Nobody calls themselves BIPOC. That's another thing snotty white people do. Yes I have friends from different backgrounds, also family. Probably more than you do TBH.
The people I converse with that say this stuff, usually it's people with backgrounds probably like the average on this site. Probably quite like you if I had to guess.
This comes across as a shallow understanding of food, culture and the makeup of cities. Cities are often very multi-cultural, all over the world, and all races can enjoy that diversity and a somewhat fairer playing field (depending on exactly where you live).
