Are you English? If so woukd it bother you if she was constantly referred to as the Queen if Scotland, missing out England all together?
I'm Scottish and quite happy for her to be the Queen of England.
She's also Queen of Australia, Canada, Barbados, Saint Lucia and I think 11 other places.
I don't think anyone is going to mention all of them when they speak about her, so why worry about missing Scotland, Wales and Northern Ireland?
