I've read that before...personally, I believe that every immigrant to the United States should have to demonstrate fluency in English before being admitted to this country.
Signs in spanish, announcements in stores in spanish, products with spanish all over them, ATM's asking me if I want to do my transaction in spanish (What? This is the U.S.!!!), press one for spanish, etc.
I am very close to having the phrase "Speak English" put on all of my shirts.
"No habla ingles? No habite en Los Estados Unidos!"
