I can only assume I don't get your first sentence because the sarcasm key has yet to be invented but I don't understand how your solution could work in reality. How do we pick out illegal immigrants? Do we just round up everyone brown or do you make all Hispanics where some sort of scarlet letter? What about my state where many of the illegal immigrants are from China, India, Canada, etc... Do they get a free pass?
So you're solution is to what, cut illegal immigrants off from society? Good because the best thing for an impoverished minority group in the USA is for their children to grow up illiterate and have no useful skills, awesome. So you want to end public schooling, Medicare, all civil service jobs, to get the constitution back to its original spending pattern? Wasn't it supposed to be a fluid constitution, that's why we can amend it? If we did everything as the constitution said we wouldn't have to worry about Mexicans becoming citizens because they wouldn't even be people, but I guess that's how it already is for you.
