actually bob, that is not true for many hispanic/latino groups.. In New Mexico, there are 4th and 5th generation families that still speak spanish.. and it is also true in NY. It has impeded many PR's progress in US society that they, and there children, and grandchildren never really learn english.. (Local impression of NY's bi-lingual education program-- the opportunity to be illiterate in two languages.. )

but different groups behave in different ways..

There are some hispanic/latino groups that behave like other immigrants -- all their children change there names from Jose, to Joe, from Consuella to Connie..

in NY there are dominicans, south americans, (colombian, peruvians, and venezuelians are most common), and central americans, and Mexicans, and cubans (more in NJ than NY, but we have a lot.) and spaniards, as well as the PR's. . I work with a number of hispanics.. one from dominican republic, one from spain, 2 from colombia, and 1 from PR-- they, like english speakers from other lands, have different vocabularies.. and different idioms.. and different cultural references, and their own set of prejudice.

Its impossible to simple mass them together and say "hispanic" and think that you can use that word to define them -- Just as a we don't often use european.. we say dutch, or sicilian.. and have different expectation of what each of those europeans would be like, from temperament, to physical appearance, religion, food preferences, to culture..
