Re: A question (completely OT)

As the rest said, you have to take into account that Americans are over 300 million English speakers spanning a whole continent, most of them monolingual (I am including Canada, and I'm tempted to include the English Caribbean). America still receives a lot of migrants, despite the laws making it harder these days: it is proven that their American-born children are likely to speak English at home and be more fluent in English than their ancestral language - and this is true even for Hispanics, in spite of the fears of English-only movements. The linguistic island of Québec is not growing in area (though it seems to be deepening). The competing ocean of Spanish is, as I said, not expanding north consistently. Overall, the USA remains mostly monolingual, and is likely to remain so.

Only other two large in area and large in population language communities exist in the world: Latin America and mainland China. And like the USA, Latin America and mainland China are also among the most monolingual places (well, if you are a Han Chinese or a Mestizo Latin American. Native minorities have to be fluent in their language AND the official language).

But then of course, as you said, a) it is not that bad to go to a country whose main language you don't know, and b) English is well diffused enough that it shouldn't really be an issue for Americans. But try to convince them.
