FWIW, I agree with SGB that it is child abuse.
If you cut the tip of your baby's finger off, it would be child abuse. If you cut off your baby's ear, it would be child abuse. If you cut the hood of a baby girl's clitoris off, it would be child abuse. It therefore follows that if you cut off your baby boy's foreskin, it would be child abuse.
There isn't any other way to put it, for me. Technically, I am Jewish because my mother's mother's mother was Jewish. But anyone trying to cut the foreskin off any of my three DS's would have to kill me first.
My Uncle wasn't circumcised, as my Nan disagreed with it. My Dbro wasn't circumcised because my Mother feels it is barbaric. And my DS's weren't circumcised because as far as I'm concerned, it's child abuse.
Acceptance into a community that cuts bits off their baby, well, they can keep their acceptance and shove it up their arses as far as I'm concerned. I want no part of a community that says that you have to mutilate your baby DS's to be a part of it.
Nobody could persuade me that heritage and belonging is worth mutilating my children for.
If my DS's choose at a later date to be circumcised, then that's their decision. But no way was I making a unilateral, non reversible decision to cut bits off my baby (!) when they weren't old enough to make an informed decision themselves.
