No, it's like saying all Protestants are Catholics. Like Judaism, Catholicism was first. Jesus Christ said he was bringing a new covenant, and you could pretty much ignore the old one. However, the way Christianity is often actually preached, at least in the U.S., they might as well be following the Old Testament fire n'brimstone prophets and not even looking at anything Jesus said. Jews can marry anyone they want, but there are many Jewish sects (like of any other religion), and each has different "rules". Most Jews in America are not orthodox. I am related to some Jewish people, without being Jewish myself, or coming from a Jewish family. Judaism was and is significantly more influential in the world than Shintoism. I also don't think Confucianism should be classified as a religion, but I guess that's the best place to put it from the given choices.
