true facts about the jewish holiday (Hanukkah).?

Once I read in a book about Jewish, that in order to celebrate the Hanukkah, they have to make a Christian priest bleed to death (not killing him right away) and use his blood to bake their cookies and after that they will go around to share out their fresh baked cookies with the neighbors (that is cooked with a poor Christian religious person or priest, even a child). As a Christian I feel so nasty toward these people…what do you think about it…
