A garbled local dialect losing much of its original connection and understood only by...True locals!
This would already describe French as spoken in Quebec. Just ask anyone from France. Tabernac!!
English is the lingua franca of the world. In the EU, where it has overtaken French and German as the language of choice in the European Parliament. In the Middle East, where it's commonly spoken. In former British interests like India and Malaysia. Even the Chinese are moving rapidly in learning English as it is the language most used in business. It's no longer the "Queen's English", it has been very much tailored to various regional dialects! ("Singlish", "Indlish", "Chinglish")
I think the point of the article is that people like this clown need to realize the world has changed, that language is about practicality and not entitlement. The only point he's proven is that he hasn't gotten out of Canada much lately, and that common sense is dead.
