There seems to be an element of the anti-immigration crowd who think that we can make spanish go away. But I don't think that any language can be outlawed under our constitution. If we do outlaw a language, then the next short step, imho, is to outlaw the content of speech.
btw, the bi-lingual belgium is currently unable to form a government among the flemish and the walloons (I forget which ones have the stars on their bellies).
Also, isn't it an irony that neither faction in belgium speaks belgian, but each borrows another country's tongue? The flemish majority speaks dutch, while the walloon minority speaks french. And how is flemish the adjective for flanders. When social anthropologists go to hell, is it belgium?
As an aside, is there any correlation between the number of "world" organizations domiciled therein and the degree of governmental dysfunctionality. That would explain a lot about nyc (aka rudy-land).
If I ever write a book it will be about sanctioned language as a tool for oppressive government.
