Mr. Leal's shout of "Viva Mexico!" on the commencement of his quick, state-funded trip to Hell, indicates a pressing problem with Mexican immigration generally. Many Mexican immigrants, legal and illegal, feel little or no loyalty to America.It's true that this is a nation of immigrants. It's also true (although you won't read this in the WaPo) that this is a nation formed of assimilated immigrants.
I'm willing to be persuaded that large numbers of unassimilated immigrants aren't a problem, but I haven't seen any good data on it. Quite frankly, it looks like nobody who could do this research wants to do it, which makes me suspicious.
