The U.S. can be very odd on the heritage question. I grew up in Minnesota, which was settled--as in settler colonialism--in the 1860s and 1870s, so the idea of "our ancestors came from somewhere else" was normal and acceptable. Of course, that "somewhere else" was almost exclusively northern Europe. In other states, there seems to be much more tension against the great waves of immigration from 1880s to 1910s when the "somewhere else" was mainly southern and eastern Europe. But no, today no one in the U.S. asks a whyte person where they are originally from.
