I understand now what you were saying in the previous post. It is interesting how you are using Italy in this post because
the Holy Roman Empire was so big at one time.
The Roman Empire and the Holy Roman Empire were big and far reaching, but that didn't mean that everyone in it spoke Latin. Case in point is the Eastern Roman Empire, which, I believe after the Iconoclast controversy, had already ceased using Latin as the state language in favor of Greek...while the state language of the Western part of the Empire was as yet still Latin.
I am not disputing that English, as it is the language of the Republican Federation of the states of America, ought to be used in public commerce. I am saying it's not anybody's business what language I speak to my sister on the street, and it shouldn't be a prejudicial aspect.
