Pure silliness. I happen to think it's no big deal. And so do most other Americans, if you asked them.
We've had bilingual stuff here in Texas for 15 years, so I guess I'm used to it. There's no evidence Texans aren't together, including the Mexicans. We voted for Bush to the tune of 70% in 2000, and 40% of the Mexicans voted for him.
I admire anyone who can speak two languages or more, and any Mexican who wants to make something of himself knows he and his family have to learn English. Most do.
This has nothing to do with being able to speak more than one langauge. The issue is whether those born in America should have to learn Spanish in order to assimilate to the immigrants, rather than the immigrants assimilating to us by learning English. Apparently, you think this is no big problem. Most others do, which is why--as demographer William Frey of the University of Michigan has demonstrated--native-born Americans tend to leave any area that becomes inundated with immigrants.
Under the Bush plan, though, we won't have any place left to go, because every portion of the country will be inundated by all the new immigrants: the Bush plan imposes NO numerical limits on the number of new immigrants who can come here.
