Calling it "mutilation" is simple hysterics and does nothing for the debate. As crip points out there are reasons actual medical reasons for the procedure and it should be left up to the parents in conjunction with a medical doctor.
Also I think going after another poster with a logical fallacy regarding his religion (in this case "jewish") is equally a piss poor tactic here,.
There are three main reasons for circumcision but doctors disgree on how promptly circumcision should be offered as the treatment. Some see it as a last resort; others will suggest it sooner.
Medical stuff:
Phimosis In babies, the foreskin and the glans develop as one, only separating during childhood. As a result the infant foreskin is frequently tight and inelastic. Some doctors may suggest circumcision in these circumstances. Others say that generally the foreskin loosens by the age of three and that true phymiosis, which affects fewer than 1% of boys, is very rare before the age of five.
If possible, watchful waiting is sensible in suspected phimosis because the vast majority of foreskins loosen themselves naturally. While only 4% of baby boys have a retractable foreskin, 98-99% of 18 year-olds do. The figures are from the British Medical Journal, 1993, the same article that revealed that many surgeons simply cannot tell the difference between an everyday tight foreskin and true phimosis.

Balanitis In Balanitis the glans and/or the foreskin become inflamed. It can affect men of all ages including boys (most commonly around the age of three or four).
Poor hygiene, a tight foreskin), skin disorders allergy to products such as soap or washing powder or to the latex or spermicides in condoms can all damage the skin and, if this becomes infected, balantitis can develop. Balanitis is not transmitted sexually but a bacteria called candida which can cause it is. Sex may also damage the skin. It is best avoided by keeping the penis clean, especially under the foreskinm but in recurrent cases circumcision might be offered. More on balanitis.
