There are some points there... thing that bothers me, is that their just variants on what was said about other immigrant groups. The Irish would make Catholicism respectable in America it was said -- and they did, but it didn't turn out to be that bad. They'd be controlled by the Pope and, as a group, they haven't. (And imagine what a Know-Nothing Party activist of the 1850s would say about a modern St. Patrick's Day parade with the Irish flag waving.)
The Jews and other central and eastern European immigrants would bring Socialism, it was said -- and perhaps, given the socialism-lite welfare state, they did -- but they were similarly assimilated.
Point is, the fears at the time of the immigration waves did not pan out or turned out not to be bad.
Irredentism could be a concern, but there is one major difference here, compared to the European examples you site. The U.S. offers the Mexicans a significantly better life than they would have in Mexico. For them to remake the U.S. in Mexico's image does not strike me as something they are likely to want to do.
Perhaps I put too much faith in the power and appeal of American Materialism, but it has worked to assimilate other generations of immigrants; I see no particular reason for it not to work again.

For them to remake the U.S. in Mexico's image does not strike me as something they are likely to want to do.They most assuredly will (though they may not want to). They lack the Jeffersonian gene and 'their' country wallows in crap. Wealth abounds in the same sphere as massive peasantry. Government corruption and zero education are contributors to this mess.
In their country, the peasants are rightfully communist sympathizers, but in our country, they're the f**king enemy.
Now, that may depend upon how well our current leaders (elected elites) adhere to the orignal 'plan' as envisioned 200 years ago and to the extent it is implemented.
Should they stray further into the land of 'collectivism', then perhaps the masses of peasant undesirables would be welcome to bring about their master plan. Peasant meet Globalist.
If, however, they should come to their senses and realize America-(it's sovereignty) is worth preserving at all cost, then these Red, White, and Green flag bearers had better prepare to have flags shoved up their hynies.
