I am deeply disheartened to see the (usual) proliferation of posts by people who clearly lack any understanding of the importance of language diversity, or the critical relevance of language retention in cultural and personal wellness.  Even more so, I am deeply disturbed by those who truly fail to grasp the simple fact that government policy, in the form of residential schools, is exactly why so many FN languages are at risk of becoming extinct.  The argument that one's immigrant ancestors eventually stopped transmitting their particular language does not hold water here.  Immigrating was a choice.  FNs were not given that choice.  Learn your history before you pass judgment.  Further than that, understand that in the rest of the world, knowing more than one language is far more common than in North America.  And there are plenty of ideas that don't translate from one language to another.  We will be poorer, as a species, indeed, if FN languages go extinct.
