Believe me...the Italian neighborhoods were not speaking mostly English in the 20s and 30s...give the hispancis a couple generations...they'll speak English...it happens every time.
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.
