I think it makes us sound stupid and a little illiterate. In every use-case (official and otherwise) the slogan of “We the north” is not even grammatically correct.
Every time I see it somewhere there’s always an urge inside of me to marker in “ARE” in between the slogan.
EDIT: it’s from some basketball slogan from the Toronto Raptors as part of some campaign that stuck. I think it’s lame due to its grammatical error in the way that they use it.
