What you are describing hasnt really been a problem. There is interaction withing communitys of various sorts, and between communitys too.

There are geographically distinct ethnolinguistic communitys like the French speaking "cajuns" in LA, and the traditional Spanish speaking populations in New Mexico. There also used to be a widespread German speaking (biligual, actually) community in the USA during the 19th and early 20th century...the last remnants of this are the old order Amish subcommunity.

Yet all these communitys did exist within the larger framework of the USA and also did indentify as Americans as well as members of their respective communitys. This type of diversity and how it is managed through poltiical, economic, and social actions has been one of the underlying themes of US history
