While the author did take some digs at the Duchess of Cambridge, referring to her as "Middleton" instead of "Kate Middleton" wasn't likely supposed to be offensive. Granted, it's silly (and misinformed) to refer to her by her maiden name almost three years after her wedding, but if she were still going by "Kate Middleton," using her last name in the context of an article wouldn't be offensive. In fact, it would be clunky to keep writing "Kate Middleton." It's common in journalism. For example, an article about the Prime Minister would likely identify him by name initially and by surname thereafter.
Yes Broadway Duchess, I see your point -and other posters, I know this subject comes up again and again.
When "Kate" is used in an article, I think there is some affection behind that, and I often use C or Catherine for expediency in posts, though "the Duchess" is probably just as easy.
I found it quite jarring Broadway Duchess when, years ago, Mrs Thatcher started being referred to as just "Thatcher".
(And we saw were that lack of civility and respect ended up, with the dreadful behaviour of some in the UK upon her passing.)
Same thing in Oz with our past female PM when reporters went from Julia Gillard to just "Gillard".
(Never was "Ms Gillard" though male PMs and MPs do get "Mr Surname" quite frequently.)
We also had quite a bit of just "Julia, but that was as a diminishing tactic, not out of goodwill or affection.
It would be nice if the media could grasp that the general public doesn't need pandering to at the lowest level of understanding of a subject.
We could probably all follow who the Duke and Duchess of Cambridge are - epecially when there is video footage, or a photo in the paper - with their report.
Cheers All, Sun Lion.
