As the other person said, I'm not against cultures, just that it's a bad reason to isolate segments of humanity into ghettos of language.
Plenty of people commemorate their cultural heritage without demanding exclusive use of the language. They are separate things, but too easily confused by more short-sighted, prideful people (the Quebecois and French are a good example of this). I suspect this is more rooted in our hard-wired tendency toward xenophobia (i.e. fear of things 'unfamiliar').
As I also stated, they could choose Esperanto or Spanish... just pick something and stick with that as a language. It is rather ridiculous that software can get hung up on localization... it's a huge waste of resources, both in development, as well as in the bandwidth/storage used.
A great example are some of the latest games that came out, like Watch_Dogs, that ran 50GB just to localize all of the audio in the game for hundreds of languages. It's nice if you are Khazak, but the effort and resources are disproportional to whatever has been gained.
Lastly, I'll also add that 'Murica has had no problem exporting its culture through movies and games, even when they are dubbed in other languages. Clearly that has little to nothing to do with the heart of a culture.
