Latinos are already much better integrated than Irish, Italians, or Germans were when they arrived in large numbers. Indeed, Latin American culture has made a such a deep imprint on the United States that it might fairly be considered a constitutive element of American culture as whole.
How do they figure that Latinos are better integrated than Irish, Italians, or Germans "Were:" back when?
Between 1/4th - 1/3rd of Texas speaks Spanish as their first language.
I can't remember when that concentration of New York spoke Italian as their first language, do you?
As for Irish it's pretty ridiculous to even include them, Irish were integrated to English culture on arrival.
Irish people in Ireland it's self almost all speak English first, and furthermore they eat similar foods like Bangers, and Mash, or Fish, and Chips, and Lamb Chops.
I fail to see how Irish people could possibly be less integrated than Texas Mexicans are?
Please do enlighten us on this ridiculous theory.
