Fair point, but the much to the chagrin of other Americans the US of A citizens seem to get a lot of acceptance for their use of the word. And it's pretty clear from context here what's intended.

Which continent would that be?

I understand that naming the US as America can bother some people, specially in countries where it is taught that America is a continent (like here in Brazil and in some places in Europe, from what I've heard), but I can't see how this point brings anything useful to this conversation. Anyway, it is just a naming convention that is taught differently in diferent places, why should it matter?

Hey, if we're getting picky it's two continents.
