I am fairly certain that most people in the non-English speaking world will also be able to place Canada on the map - I'd assume the French know exactly where Canada is. But I digress; it's not about placing a country on a map. It's more about we know that Canada is a separate country, and it has an identity distinct from other countries in its continent.

This goes beyond mere politeness; that you used this word is a bit suggestive. Refusing to acknowledge an identity is far more than just a lack of politeness.
