I was thinking about this not realy knowing why it was done etc so i dug up this page with some interesting points from a jewish mothers view of circumcision she makes some very interesting points regarding its origins
"The biblical injunction to circumcise speaks to a man about men. But circumcision is also a woman's issue, for on a subtle, but very potent level it is, like the akedah, about the primary disempowerment of the mother. At no other time is a woman so in touch with her most elemental and powerful mammalian instincts as after a birth, When, her culture tells her that in order for this male baby to be a man, to be part of the masculine community and bond with the male God, the men must cut her male baby on his most sensitive male organ, this mother is inevitably in conflict with her entire life-giving feminine biology. And if a woman is made to distrust her most basic instinct to protect her newborn child, what feelings can she ever trust?
This violent disruption of the maternal-infant bond is not an accidental consequence of this ancient male bonding rite. It fits the pattern of a multitude of rituals that are prevalent cross-culturally which serve to disrupt the very delicate early hours and days of maternal-infant bonding: tight restrictive swaddling, foot binding, early baptism in cold water, smoking of the newborn and mother, ear piercing within the first hour of birth, etc. Circumcision is one of the most violent of these rituals (Odent, 199 1)."
