As the United States gears up for a political brawl over immigration next year, one of the concerns shaping the debate will be the fear that English-speaking Americans will be culturally and linguistically overwhelmed by newcomers, many of them Spanish-speaking.
An example of what is in store was the autumn cyberspat between the Telemundo anchor and MSNBC host Jose Diaz-Balart and the talk radio host Laura Ingraham, who was annoyed because Mr Diaz-Balart had pronounced a Hispanic name with the correct accent and conducted a bilingual interview in too "herky-jerky" a manner.
For me, reading about the contretemps in the lobby of Canada's House of Commons was a moment of cognitive dissonance.
In our Parliament, Anglophone members speak terrible French every day. Our accents are so bad that sometimes our Francophone colleagues cannot quite hide their winces.
This butchering of Flaubert's native tongue is the foundation of a larger accommodation that Canada, and in particular English-speaking Canada, has made with a world in which our language may be dominant, but isn't alone. We are far from perfect - our failings are particularly egregious in our treatment of our aboriginal people - but when it comes to living in a multilingual, multicultural world, we get a lot right.
"Multiculturalism isn't just about statistics, it is about attitude. It is about seeing diversity as strength," Mr Henry Kim, the director of Toronto's dazzling new Aga Khan Museum, one of the world's finest collections of Islamic art, told me. "Canadians believe that blending makes you better and stronger."
Mr Kim is a Chicago-born Korean-American. He doesn't speak Korean, and his mother baked apple pie "badly". He suggests that his homeland is still uneasy about incoming cultures: "Canada has a minister of multiculturalism. Can you imagine that in Washington?"
One of his favourite examples of Canada's embrace of diversity is Little Mosque On The Prairie, a sitcom about exactly that.
Mine is a "social experiment" staged in Hamilton, a working-class city south-west of Toronto, after the death of its newly and tragically famous son, Nathan Cirillo, the reservist who was shot in Ottawa in October by a gunman who had expressed sympathy with radical Islam.
One actor stood at a bus stop in traditional Muslim dress. The other loudly argued that the Muslim could be a terrorist and tried to stop him from boarding the bus. Over and over, bystanders defended the Muslim-looking man. The experiment finally had to be stopped when the actor playing a bigot was punched by an offended local.
That's hard to beat as an advertisement for healthy multiculturalism. One reason for rejecting a mosaic in favour of assimilation is the fear of the opposite outcome, that immigrant communities that hang on too tightly to their original language and culture will fail to integrate into the larger society.
But research shows that immigrant children raised in an environment that values the language of their parents actually learn English more quickly and are more academically successful. Part of it is psychological. Multicultural societies make immigrant children feel accepted in their own right.
The advantages of bilingualism seem to be neurological, too. We are wired to learn languages, and the more languages we speak, the more networks our brains develop.
I suspect the greater, unspoken, concern of Anglophones is that we will be at a disadvantage in a society where everyone else is bilingual. I get it. I feel that pang every week when I stumble through my French class and then listen to the perfect French and English of my native Francophone colleagues.
The world's rich countries are falling into two camps: those that are able to attract and welcome immigrants and those that are not.
Western industrial societies like Japan and parts of Europe that are unwilling to accept newcomers, and to allow themselves to be transformed by those immigrants, are destined to demographic and economic decline.
Citing a number of recent studies that show a connection between immigration, diversity and entrepreneurship, Andres Rodriguez-Pose and Daniel Hardy of the London School of Economics recently warned that this year's hard anti-immigrant turn in Britain would have negative consequences: "Recent legislation by the UK Home Office to restrict migration is likely to lead to a serious dent in entrepreneurship, affecting in turn the potential for employment generation and economic growth."
Multiculturalism and bilingualism are hard. A couple of weeks ago, an MP from Quebec chastised the Canadian government for using the verb "captiver" (to captivate) on its Twitter account instead of the correct "capter" (to capture) and accused the Twitter-feeder of mechanically translating jokes word-for-word from English. Quelle horreur!
His insistence on linguistic precision points to the real challenge of a bilingual or multicultural society in which one language and culture is dominant: keeping the minority cultures from vanishing.
Anglophones on our shared continent shouldn't worry that our children will speak Spanish or French. We should be afraid that they won't.
