@musicman I don’t think you’re missing anything. They’re saying it is all non-whites (POC), but more specifically Black and Indigenous North American people.

I don’t agree with the article. If you mean Blacks, say that (and don’t say “African American” ... for a good sized segment of us, that is offensive; in part because it was tagged onto us from the outside, not chosen by us). If you mean Hispanics, say that. If you mean Asians, say that. And so on.

Within each broad grouping, if the person or people you’re referring to all share a more specific ancestry group, refer to that instead of the broader group.
