Be that as it may, there are many examples here of people not wishing to adopt a recently-invented term to describe themselves even though it is found convenient by others.
On a related question, which I find interesting, how do people feel about being called “Anglo”? Several years ago I was participating in an online survey site, based in California. At some point, there was a series of questions about ethnicity, and possibly race. I don’t recall all of the details now, but I do recall that the term offered that was obviously meant to apply to me was “Anglo.” I had never encountered this before, and I recall feeling not only taken aback, but irritated. My ancestry is Scandinavian and Celt, not English, and as a matter of fact the Celtic part of me has historically been very much at odds with the “Anglos.”
