In the US everyone came from somewhere else, so there is a bit of pride about your heritage. I think people are so many generations removed now they understand it’s their heritage, not their identity. I have English, Scottish, Irish, Croatian, French and Italian heritage. Some of my ancestors got here in the 1700’s, some in the early 1900’s. It’s part of what makes us US Americans. The only ones who were originally here were the Native Americans, who everyone fucked over and stole their land. I don’t think any of my southern ancestors had slaves, they were poor indentured servants, but I think my midwestern farm folk killed a few Indians.
