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?


Not fully accurate. Race is a system of categorization that was invented. The systems of categorization that is used around the world under the term “race” today are all derived from a single system of categorization that traces its roots back to 14th century Portugal and a single author, Gomes de Zurara.
I don’t see how that helps the validity of race as a concept.
