Answer:
Being a Jewish person is somewhat of a "special case" in that Jewish people are frequently referred to as a race or nationality when in fact they are neither. Jewish people cannot be considered a race because their numbers have been augmented over their long history due to the assimilation of people of many different races. Despite the fact that the nation of Israel exists, Jewish people cannot be thought of as a nationality because over their history dating back over 2000 years, they have been dispersed across the globe such that people of many different nationalities are Jewish. However, Jewish children are born with "Jewish identity" by virtue of the fact that they are born of Jewish parents and are considered Jewish even if they do not actively practise the observances of their faith. Finally, one can identify a religious Jew by the way they actively practise their faith in the same way that one can identify a person of any other religion.
