nicci, I'm not an expert in history or geography so please forgive my mistakes on that part, my spelling, etc. But I know for a fact that I am right in my point about the meaning of ethnicity.

You say ethnicity "refers to a shared and common cultural heritage amongst groups of peoples", sorry, that's the meaning of CULTURE. A shared/common cultural heritage amongst a group of people IS their culture.

Nationality does not refer to a person's "blood" history (ethnicity), such as Italian, Russian, etc. Nationality DOES denote an individual's belonging to a NATION.

All this info about ethnicity, culture & nationality is in the dictionary (check if you do not believe it). If you so much enjoy debating & educating the not so knowledgeable, I suggest you pick up a copy so you are well armed with the correct information.

By the way, Jewish is a term used to describe an ethnicity AND a faith, though independently of one another. Just as there are people of other ethnicities who practice the Jewish faith, there are also people of Jewish ethnicity who practice other faiths.
