He finds gentile culture alien and foreign. He has his own language, religious practices, dietary restrictions, mode of dress, and beliefs. On the other hand, he is a resident. He is a citizen of his adopted land and is totally integrated into Hittite society. The reconciliation of these two disparate forces exemplify one of the historical tensions in Jewish life.
People feel torn, compartmentalised.
They wear a yarmulke in Shul, but they take it off in the street. They tell Jewish jokes among their friends, but they try to act like Gentiles the rest of the time. Such behaviour turns off scores of young Jews, who leave their insulated Jewish worlds, go to universities like Oxford, and suddenly find themselves in unfamiliar territory. Instead of developing a mature, healthy synthesis of both their Jewish and general worlds, they tend to discard their Jewishness because of their inability to reconcile the opposites they now so intensely feel. Everybody wants to fit in and young people feel uncomfortable celebrating their Jewishness in a profoundly non-Jewish environment.
