they don't want to integrate, they want to live their same way, want to speak their own language, don't want to learn to speak the language of the country. They want to form their own enclaves, they want to forge a part of their home country in America with their way and customs of life, in short they don't want to be Americans.
That exactly describes the extreme Religious fundamentalists 'The Pilgrim Fathers' who arrived on the Mayflower at Cape Cod, Mass. in 1620

They didn't want to integrate with the other Christian settlers, so set up a single Religious state and even hung two Quakers who refused to convert
