I have written at great length about circumcision in the past, so I don't want to go on too long here. I just want to make one point.
I have read, from other opponents of routine circumcision, analogies between the pro-choice position on abortion and the anti-routine circumcision stance. This is a natural enough connection for me, as I fall into both camps, but I am very leery of this kind of equivalency. Political situations are always individual and idiosyncratic, and so political discussions of various issues always have to unfold according to their own internal logic. Analogizing issues like circumcision and abortion too closely invites distortion of each, and people have (understandably) various sensitivities about political "turf." So I would caution anyone against making this kind of comparison too easily or in any kind of comprehensive way. However, there is one set of shared principles that I think are worth looking at in these issues, a facet of each discussion where the political and moral reasoning seem close to identical, to me.
You occasionally will hear from opponents of abortion who wonder what the big deal is about carrying a baby to term. They can't imagine why doing so is seen as such an imposition on the woman. (Lest I be accused of engaging a weak man, this is of course not the only or primary argument anti-abortion advocates use.) Now, to me, such reasoning is entirely unconvincing. I can imagine all kinds of ways that carrying a pregnancy to term is difficult for women, and have read many first-hand accounts from women on just how difficult pregnancy can be. Likewise, I can imagine many ways in which having a baby can be socially or economically crippling to a woman, even if she plans on giving the baby up for adoption.
But the truth is, it doesn't matter what is apparent to me, or convincing to me, or what I can read or understand or imagine. It doesn't matter. What matters is that I respect the right of women to make that choice for themselves and their bodies. I can't inhabit the life of another person, particularly someone of another sex, and so I can't meaningfully understand her choices. I don't have to, to support her right to choose. I only have to recognize that some of the most elementary human rights are the rights to be sovereign other ones own body. Me, personally, I'm compelled by arguments about how hard having a baby or supporting a baby can be. Doesn't matter whether I am or not.
This is where the one similarity to circumcision comes in, and it's important. Often times, in this debate, you encounter people who take it as self-evidently absurd (and, often, funny) that anyone could be emotionally invested in the presence or absence of foreskin. You get these dueling sets of evidence, about STDs and penile cancer, and about pleasure reduction, etc. To me, trying to convince people empirically that the foreskin is important is exactly the wrong way to go about having the argument. Because just as with a pregnant woman and her choice, it is absolutely immaterial that anyone else be able to understand why a man might feel one particular way about his foreskin. It really doesn't matter if anyone on the Internet can be convinced about his feelings. It only matters that we recognize that it is his body.
This is complicated, of course, by the fact that circumcision, unlike abortion, almost always happens to infants who are incapable of choosing or understanding the choice. (Which is interesting.) Unlike some who are opposed to routine circumcision, I can't go so far as to advocate taking the decision away from the parents; parents have to be responsible for the medical decisions of their children, and circumcision remains a medical procedure. But I do strongly urge parents to really think about it, and to give strong weight to the fact that the infant is a human being with a human being's ownership of his own body. Many people seem to circumcise their infant boys out of a vague sense that it's just what's done, not out of religious conviction or appeal to the (seemingly negligible) health benefits for those in the developed world. That seems to me to be a terrible imposition on the right of the child to control his own body, without much justification at all.
And, remember-- the procedure will always be available to him. If he gets to be an age where he notices and cares about the fact that he is uncircumcised, he can always have the procedure performed. If he does, it will be his choice.
