I come across many hispanics who have been here for decades yet have made no attempt to learn English. Italians who are like that are no better, or is anyone else.
Additionally, Italians never ever demanded that America change its ways and customs to accomodate them. You simply cannot say the same for immigrants of today coming from South of the Border.
If I were to go to France, I don't believe everyone there should accomodate me. My expectation is that I accomodate their ways.
Again, you are talking about hispanics who came "here" from "there." It may have been several years ago...to them, if they grew up there, it was yesterday.
Its the kids who assimilate...they are the ones that grow up baseball Yankees fans (not soccer Aztecs fans). They are the ones that learn the language...trust me...it happened with the Germans, the Italians, Russians, Ukes, Poles, and the Welsh...it will most definitely happen with the hispanics...
