Sorry gotta agree with HeyIts-Quotev_Gurl3 here. Well not really sorry, but Semantics amiright? Anyway, this is exactly the same thing Gobbles said about the Jews and other Non "Aryans" So...
Language is a barrier indeed. But to deny a Person the right to enter and even attempt to learn the language is quite frankly illegal, unmoral, unconstitutional and against UN Charter (I think, atleast in the EU it is, that I know )
I don't think you got what America is all about. I mean the Indians didn't complain that you couldn't speak their language. Then again... you DID kill 99% of them. Perhaps your on to something.
