Jesus *isn't* a Jew? He was born of a Jewish mother, in an almost exclusively Jewish part of the world, Galilee. Galileans were displaced Jews from the Hasmonean dynasty displaced by king Herod. Herod was the client king of Judea. His mother Mary was visited by niggers and Arabs bearing gifts because they didn't know if they were the father. All his friends were Jews, his disciples, all of them were Jews. He went on pilgrimage to the Jewish Temple in Jerusalem where he was under the authority of priests. He celebrated the Jewish festivals whilst preaching his mission, Jesus even celebrates Seder Passover in the bible and it's debatable whether this is depicted in the last supper. Even if you separate the religions entirely through some miracle of geography, history, lineage, themes, chronology, several identical chapters that appear in both religions, and say he was the first Christian. He was still ethnically Jewish. It's more Jewy than the sitcom friends.
