We have a new user called Asian but no Chinese. It's not spam, and I guess it's not offensive, but it seems … weird. I couldn't find a tag related to username issues on the only other post I remember about, uh, username issues, which is MO policy regarding pseudonyms that are other people's real name. Is it appropriate to suggest the user change it to something else?
EDIT: There's some very interesting discussion in the comments, which I'd be glad to see continue if it's not inappropriate; but @YCor has already made the suggestion, so I regard this question as answered. In fact, if @YCor or anyone else wants to say something to that effect, then I would be glad to accept it as the answer.
