The big deal is that if someone took a sharp object to your privates as a baby or child without a valid medical basis then they essentially took away your agency over what happens to your own body. Which is wrong.
In the name of religion? Okay, so if Catholics had their way abortion would be utterly illegal. Would you want some diety worshipping busybody telling you what should happen to your own body and then make you feel angry because they want to control your sexuality, and all because someone somewhere thinks someone else has some God-given right to take away your right to your own body?
I would be beyond furious. I always use the abortion argument analogy here because it makes perfect sense. No one owns your sexual anatomy. And that's what this child mutilation is. Let's face it, infant circumcision had its roots in trying to curb masturbation. That should put anyone off the idea just to begin with. Your body belongs to no one else.
I don't have a problem discussing circumcision ethics. That's different than telling men that their dicks are mutilated. Mutilation has a very specific connotation. It's what happens to people when they are injured during war, subjected to torture, or a botched medical procedure that has no therapeutic outcome. It's considered a disfigurement. I don't consider circumcision disfigurement. It's simply not the same thing.
I find that the anti-circumcision brigade doesn't differentiate between these things, and so they end up losing my support. I agree there is an ethics issue surrounding involuntary circumcision in babies -- I could give ground to that. But don't tell cut guys that they are mutilated, unnatural, or somehow less than.
Some guys get cut long after infancy for medical reasons, and they live much better lives because of it. You have no business telling them they are mutilated.
This thing we're doing here of isolating a body part in space is very objectifying and denies the whole human being it's attached to. It's kind of fetishistic. For a time I was very distraught after reading anti-circumcision rhetoric because I temporarily bought into this idea that something was wrong with me. It even drove a wedge between my parents and I for a while. Then I started having sex partners who liked my dick, and now I see that there's nothing wrong. I didn't have a problem with my body until someone suggested I was mutilated. Also, my parents acted under standard medical advice at the time, advice which has now changed in Canada.
I got angry, but at the end of the day the anger didn't serve me because I can't change it. Since I'm never having children, I won't even have a chance to raise an uncircumcised son. Like I said, I prefer circumcised dicks because they are cleaner and never smell weird... but I wouldn't reject a guy for having a foreskin. That's stupid.
