I've lived most of my life in the north, and I think what Dennis Bevington was saying is there are some principles that are intrinsic to government, such as working together, collaborating, helping each other, and working towards the common good. Those kinds of values are part of the nine indigenous languages that are part of the 11.
If we're not walking that talk in government, then you can use the Tlicho language or any of the languages, but if you're not demonstrating that in action, then it's meaningless and the elders will point that out.
