I agree that immigrants should learn to speak American English, as much for them as for everyone else, however our country would be bland indeed if they are expected or enforced to leave their culture and heritage behind. I think that our diversity is one of our strengths! We are already too much a product of cookie cutter and chain businesses, regimented schooling and biased media. Immigrants bring us extra flavor!
How many of us call ourselves Irish Americans, or African Americans, or Mexican Americans?

How do you feel about the quote from Teddy Roosevelt?
