Gawker also picked this story up.
Anyway, this is nothing new, at least in my opinion. Southern rednecks, especially in the areas around Oklahoma, Texas, and Alabama, have this weird tick that sets them off: it's foreign immigrants who they vehemently believe "refuse" to learn English, just to make life hard on them. There was a thread somewhere near Tilted Entertainment that was going the same way as well.
The thing is, up until 3 or 4 hundred years ago, those states belonged to either France, Spain, or Mexico, so the whole "be American and speak American, or get up and move on" shtick is really a contradiction, as they aren't the real Americans who were there for generations before.
