Classic wannabe citizen of the world argument. Meh, it changes from the redneck arguments against bill 101 that we get from the west.
It is nonetheless invalid. North America is probably the only place in the world where languages other than english are seen as a handicap. In fact french is our singlemost important asset and we must protect it with claws and beak. It unites us, defines us and makes us stronger against the global cultural flattening that plagues human civilization. French is an international languague and we do benefit from the special relationship we have with other french speaking countries. It is not the language of a unique country, like you said. Even if it was, it's not a valid argument. Some of the countries that have the most thriving economies and the most pleasant social climates in the world also have some the most exclusive languages (I'm mostly thinking about northern european countries here).
We must work towards a bilangual society that puts french in the first place. You have to be nuts if think that quebecers will give up on their culture for some illusionary economic argument
Peace!
