When my Grandparents were still kids, if you had to go to a court in most parts of the state and you spoke only English, you'd need an interpreter.
WWI and WWII devastated the German community and they became fully assimilated. Today people like Senator Lugar are well respected and they use English quite well, all things considered. He's a real credit to his race, eh?
Now, these Hispanics? Would it help if we conducted a war against Mexico or something? Certainly they are at least as smart as the Germans were and they'd get going on that assimilation part right quick. Maybe just a small war - that'd do it - run a couple of humvees over to Juarez and demand their surrender.
It would help if we at least had as much of a BORDER with Mexico as I do with my friendly neighbor!
Why is it so much easier to illegally enter the U.S. from Mexico than to illegally enter my backyard - over a 5' chain-link fence all the way around, with anticlimbing slats, plus unpredictable dog-run times - from my neighbors'?
