The rigorous protection of human rights, the life of smaller languages, the environment is almost always counter to the interests of government and big business. So ordinary people have to struggle for language rights. There has to be an awareness that the policies of 19th century nationalism, the ideology of one language-ism cannot work and are bad for people. This is the mystification of a language. National culture and tradition, ethnic history and so on are mostly a clever invention.
Culture easily becomes a cult.
Language, culture are not the private property of particular groups or nations. I know there are lots of paradoxes in all this, but in the end we have to keep reminding ourselves that it's just people that speak language not abstractions like a nation or a culture or ethnic group. I began learning Japanese about 15 years ago. When I look at young people on the street, it seems like they're speaking something that I never learned in the classroom. The languages that don't change are those which are fixed into a writing system, like Latin or Greek, and which don't have a speaking population.
