One (just one) properly conducted study showing that infant circucision leads to sexual disfunction or a loss of pleasure as an adult.
So, you're actually saying here that if you were provided with a "properly conducted study" showing this... what, exactly, would happen?
Somehow I don't think that this would convince you of anything. After all, you need to look good for God, which was Reason #1 listed below -- obviously the first one that came to your mind. Surely he's more important than sexual function... after all, isn't it also a sin in His eyes when you have sex outside of wedlock? If you're going to permanently alter your child's body for your religious beliefs (or the religious beliefs descended from your ethnicity), you might as well go ahead and follow the other beliefs of the faith. Sex should be about procreation, not recreation, right?
So as far as I see it, you would (or should), by some of your very own arguments, consider the question to be irrelevant.
Obeying the revealed word of God;
Not a very convincing reason. I don't accept the "revealed word of God" to justify any other kind of abuse towards a child. Not to mention that the God-claim is so patently ridiculous, considering that the source comes from men who considered stoning and killing people for, say, working on the sabbath as utterly moral.
Family membership in a close-knit ethnic group;
I'll never understand the idea behind ripping away some skin to be part of an ethnic group, but okay.
Traditions and ceremonies that increase family and community bonding;
I have a perfectly fine time getting along with family and community without ripping skin off my penis. I find it sad that it's so impossible to do this in your society.
Honoring the sacrifices of one's ancestors (as recently as one's parents) who were persecuted for their beliefs;
I can think of many other ways to honor the sacrifices of one's ancestors instead of forcing my child to undergo a permanent surgical procedure.
Traditions and ceremonies that increase one's bonding with one's own history;
Didn't you already say this?
Carying out obligations so as to minimize family friction and receive economic and non-economic benefits from such family members;
It's kinda sad, the idea that you can only receive economic benefits from your family members as long as you force your child to undergo a permanent surgical procedure. Those wacky Jews.
and lots more that I can't think of right now.
I'm sure the "lots more" you can't think of would entirely be just as convincing to me as the rest you listed.
It cannot. Whether you like it or not, parents make irreversible decisions for their children every single day.
I cannot think of anything quite as irreversible, personally. You decide their education? Okay, up to a point, yes. But after 18, they can go off on their own and earn their own education; ignorance is not quite permanent. I can't think of many other things that are quite as permanent. Even piercing the ears can heal up. I suppose you could always give your children permanent tattoos or something, but this isn't quite something that I see as very popular.
Plus, I do believe there are some ways of removing tattoos.
The status of parent, in fact, creates a moral obligation on a person to substitute his judgment for his child. That's the exact oposite of what you said.
And yet, society steps in and tells parents constantly when they're not acting in the best interest of the child. Child custody is there for a reason, you know.
So this is the exact opposite of what you're saying; a parent does not have free reign on all decisions when it comes to children. Unfortunately for you, it's not 100% a subjective matter that's only up to the parent's decisions. Or else, they should be free to do whatever they wanted to their child, including abuse, neglect, or cutting off their ears because it makes them holy and "cuter". It is up to society to decide what is wrong and what is right, and what should be encouraged or discouraged.
In this particular case, it is a matter of degree.
Answered, I believe, in sufficient detail above.
While there was detail, the answer is found to be wanting.
