You forgot this major difference:
ALL Mexicans are taught from day one in their official history textbooks that the American Southwest was stolen from them, it is their birthright, they have every right to live in all parts of the "stolen" land, and they do not need to obey our immigration laws, period.
Algerians cannot say the same about France.
Thought I'd point out that difference, which you seemed to overlook.
Also BTW, the Mexican state department still has the "Immigrants Guide" up on their official website, advising Mexicans how best to illegally invade the USA, and play the system once they are inside.
Travis, Actually the Moslems can and do say they once owned parts of Spain and France. So that would be a similarity rather than a difference and a case you could have used to support the thesis of the article. However, the differences I mentioned seem cumulatively more important to me.
RKV, You identified the problem that the author of the article missed. The Dim multicultural policies are the problem. You should work to over turn them so that these good conservative Catholic immigrants become true Americans and support American values. We do need to control the borders so we know who is coming in, but we don't need to close the borders.
