For the record, I don't think anyone here has attacked me personally. I did have my two sons circumsised in the Jewish tradition. While I thank Darth Rotor for his passionate defense, I don't feel I've been personally disrespected. I would thank everyone to keep the conversation philosophical and not personal, though.
Religious reasons are not specious. They're just reason you don't agree with.
Except that the literature shows that the earlier a circumcision is done, the fewer long-term effects there are. The only study on male pleasure or sexual function included only men who were circumcised as adults - long after the brain had mapped the area of the glans. The so-called "slut study," where women with multiple partners were asked their impressions, was poorly controled at best.
The best medical information appears to be that, while newborns can feel pain, they cannot locate the source of that pain. Nor are they capable of forming memories because their brains simply lack any method of definition or compartmentalization.
My anecdotal experience is that my children cried more from being held down than they did from the cut; the entire circumcision including prayers lasted about ten seconds; and they had stopped crying within two to five minutes of the bris.
All of this having been said, I have seen no compelling medical reason for or against circumcision. I would not recommend circumcision performed in a hospital, nor would I recommend it for general health reasons. I see nothing wrong with religious circumcision.
