Yeah,
It's kind of like the whole Scottish\English\British debate..
I'm from Scotland which as part of the United Kingdom makes me British. But most people from Scotland get pretty darn annoyed if you ever refer to them as English. Despite the fact that to much of the outside world, English and British are often used as if they meant exactly the same thing.
So I can understand a lot of this..Though to me artificial national boundaries to divide people seems to cause more problems than it solves..
