Kate wild has a Jewish background, so it makes sense that she has only seen male circumcision as a positive thing.
I'm Jewish and (of course..) snipped and I would not do that to a son if I had one. (My children were all daughters.)
That it destroys a fair amount of nerve endings is a fact. That it is often intensely painful can and has been empirically demonstrated by measuring stress hormones in the infant's blood. That the child doesn't remember this pain later in life and on that basis, it is therefore okay, is basically the same excuse offered by child molesters as a defense. We as a society have collectively decided that remembrance (Or more precisely, the lack thereof) is not a defense.
We as parents allow our children to undergo painful procedures (e.g. a tonsillectomy) when there is a justifiable purpose to it. That circumcision serves no justifiable purpose in developed countries anymore is also a fact.
