This is a hot-button issue for me. The fact that this supposed "god" created something so perfect and then decided it needed to be modified completely baffles me. It has nothing to do with science... maybe, just maybe, these nomadic desert people saw that it was difficult to keep an intact penis clean, what with the sand and sweat, etc. Maybe they saw the nations around them were NOT circumsized, so they did it in order to separate themselves further. In my way of seeing all this "separation" from the surrounding cultures (along with other factors like following one man who claims to be the mediator or spokesperson for god himself, etc) , it's my opinion that Judaism was the very first true cult.
I decided not to have my sons circumcised because I didn't feel it was my right to hack off a piece of their body *shrug*. Body modification is a personal choice. It's not MY body, so it's not MY right to choose to modify it. Same reason I didn't have my daughter's ears pierced as a baby. Not my choice. I did lots of research, looked at both sides of the arguement, and concluded that it just wasn't necessary and wasn't worth causing them pain over. In SOME cases it is a medical necessity, but that's rare. For the most part, as long as it's kept clean, there are no issues. Quite a few insurance companies in the US have stopped paying for routine circumcision because it is considered cosmetic and not medically necessary. If, for example, a boy was born with hypospadias, then the foreskin would be most likely to be used to correct it, and therefore, it's medically necessary. Having a boy and wanting him to "look like his father" is not lol. It becomes out of pocket to have it done. For the record, neither of my boys look like their father (in ANY way, but particularly in that area) and it's not something they've noted or even care about.
