In the 21st century Judaism is just another religion - no more and no less. Maybe in earlier times it was difficult to separate Judaism from a cultural/nationalistic sense of belonging, but today, religion is a private concern of the individual to his or her favoured deity rather than a public means of keeping the collective together and the troops in line. Just like Christians, Muslims and others, Jews will intermarry and some will convert. What's your problem with that?
