France (read: Chirac, et al) isn't exactly the USA's closest bosom buddy so that really doesn't surprise me. 
The point remains, nobody identifies themselves by what continent they're from. Nobody. So it doesn't matter what continent system you use, 5, 6 or 7, because nobody's going to be that vague. Since everybody gives their nationality, and there's really only one country with the actual word "America" in the national title (at least that I'm aware of - if there's another, I'd really like to know), that leaves very little room for ambiguity as to what country that person might be from. And hence, very little ambiguity for a culture group ("civ") unless the other party is somehow used to people introducing themselves by continent first. In which case, I dare say that other party is freakish.
If you're not used to people introducing themselves by continent first, and there is no other country with the word "America" in the title, the only real reason anybody could object to the term... is if they're being a jerk for the sake of being a jerk.
The only other possible, tangential reason I can see is having to name the entire cultural group from the Americas as "American Civs" but the distinction is pretty much implied.
And if, in person, I ever hear anybody say "United Statesian," or an identifiable equivilent in another lanugage, I will remember to take my time, point, and laugh obnoxiously.
