Briton?

Seriously though, if you move to a country you shouldn't try to change it once you arrive. Britain is a product of it's history and traditions and many of the current problems stem from trying to ignore these.

I like Britain, so I'm not emmigrating. Presumably if you are emmigrating its because you think the place you're going to is better than the one you left. So don't try to make it like the place you left, if you don't like it you can go home.
