Fairy Tales: jewish Folk tale Tradition

I find that Jewish folk tale tradition is mainly focused on religious aspects of normal life.  It compares the jewish religion to the christian and claims that jewish religion outdoes other religions.  Many of the tales had to point out the necessity of the hero being jewish.  Possibly because in older times the jewish people were disliked and oppressed by other people of different religions.  They, like the sign language community, had to create stories to make them feel better and that they had hope even though they were being oppressed.  Also like the african folk tales brings in wit and smarts to win the hero's tale.  They outdo their villains by being patient, smart, and clever.  Such as in" The Rabbi Who Was Turned into a Werewolf" which was a very great story which played on smarts and patience being the key to being the hero and ending the story rightfully.  However this story also laid out the moral not to trust women for they are truly greedy.  In other stories by jewish folk tale tradition it was clearly a tale to prove that the jewish people were stronger and smarter than the other religions.
