Point is, North Vancouver is no longer a British-WASP enclave. Cultures and cuisines mix and mingle up and down the street. And this has come about because of globalization and shopping malls and big box stores and changing immigration policies. It's not all good, it's not all bad, it just is.
Now try a thought experiment. Imagine if your kids listened to -- to take an example -- Persian music. And they admired Persian movie stars and singers. Imagine if they wore only Persian styles of clothing, or t-shirts with jumbled Persian phrases on them, or designs that included the Persian flag. And they wished they had eyes like the Persians and some even had plastic surgery to achieve that Persian look. Imagine if they abandoned playing street hockey in favor of Persian sports and hobbies. And they thought Persian movies were better than North American movies. And they planned to major in Persian at college. And wished they could go to Persia. And of course the kids regarded Persian food as a special treat. And private and public schools couldn't hire enough native-speaking Persians to fill the demand for Persian lessons.
I am of course, talking about China and the West, not Canada. Last year, China's president, Xi Jinping, promised a "great renaissance (also translated as 'revival') of the Chinese nation." Appeals to Chinese nationalism will inevitably include promotion of Chinese culture. It appears that many within the highest echelons of the Chinese government want this renaissance to include some cultural push-back. I surmise that taking English out of the university placement exam and banning popular TV shows like the Big Bang Theory, are two examples of this pushback. Let's see what else happens.
