quote from BCP : No I'm not
the other states , canada <snip>
OK. WE HAVE BEEN OVER THIS.
Canada was never annexed by the US. we are not a smegging state, thank you. (technically we're a dominion, but I'm not sure if that precludes also being a state, since state is obviously from the word "estate" which (IIRC) essentially means a land holding, so a state is really a government land holding) I have no problem with the United States, obviously. I can handle "american" because technically we are in North America, But saying I'm/we're in the United States is analogous to if I was to say that Wales, Scotland, and Ireland were part of England. I know for a fact that Scottish and Irish folk dislike being told that "they are all the same" as England.
Difference being, Wales, Scotland, England and Ireland are all part of Great Britain.
Additionally, the other countries you named appear to all be former British Holdings, which have nothing to do with states at all. They were never considered "states" to britain as far as I'm aware; the moniker was originally used evidently to imply that Canada and the U.S are somehow one and the same. They are not. They are two different countries, and two different peoples, and I'll be damned if I'll let anybody try to tell me otherwise.
In fact, in a curious twist, it is in fact the UK that are the United States closest Ally (and I am not simply referring to statements by the former president of that nature, but rather referring to import/export and trade agreements, as well as investments into each others economies. Of course Canada is also an Ally to both nations but to actually call us a "state" of the US can only be based on our proximity; which is, if nothing else, a foolish thing to say, considering, you know, scotland and ireland and wales are so close to England... aww heck, let's call them ireshire and scotshire! what the heck, they are pretty much shires of England, right?
