Not that it matters, mostly, but I do want to get the words right. So we are reading a book on someone who is mixed Native American Ojibwe and white.
Some people in my class, let’s say, are Indian (from India) and white. We agreed that would be mixed, but for example, someone who is English and Swedish would not be because they are just white.
Would they not be mixed race, mixed ethnicity, or be neither?


Your question assumes race is a real thing and not just something made up by people.
Cultures and communities are real. There’s Native American culture, Indian culture, Swedish culture and English culture. There is no “white” culture. It’s the clash of cultures than normally causes the problems we see in the world that we mislabel as “race”.
