Once immigrants arrive, legally or not, they face those who insist --demand -- that they speak English.
It's as if they are saying to the immigrants: "You'll want to know about the freedoms we allow, and the ones we don't. Yes, we do have freedom of speech, but don't you get all too carried away with that. Freedom of speech might mean having the right to speak your mind, but it doesn't give you the right to choose what language you will speak it in. If you think you can get willy-nilly that way, you'll be wrong. You cannot just speak whatever whatever language you want, especially not your own. No way. If you want to be an American, you will learn to speak our language. We find it highly offensive for you to come in here speaking an unauthorized language.
"And, we don't want any excuses. If you aren't much on picking up on another language, if you've got a learning disability or something, you better get over it. We don't allow for that. What we allow for is for you to speak English.
"You'll do things our way, and on our terms or you'll go back to where you came from."
