Why is it such a controversial thought to merely include and acknowledge the rest of Canada, rather than discounting them outright?

In case you're wondering here the divide comes from: it's this, and it's you.

All Canadians matter, every Canadian experience is valid, and no Canadian is any less of a Canadian than any other. Erasure of Canadian experience outside of the GTA is an elitist and divisive attitude and serves ONLY to create friction where there need be none.

As soon as you erase a group from the whole, it's INEVITABLE that they'll seek to find their own independent identity. Considering your proximity to Quebec this shouldn't be a foreign concept. Just feel free to extend the inclusive attitude west as well as east. It costs nothing to be inclusive of your fellow countrymen.
