It is a fact that there is NO medical reason to circumcise and the fact that the United States continues the practice, which most western nations prohibit, shows the disregard and double standard applied to males as we readily accept female genital mutilation is wrong and prohibit it. It is HIS body and should be HIS choice when he reaches the age of majority.
Further information can be found at Doctors Opposing Circumcision. The web site has a wealth of information for parents, males, medical personnel, etc.
For those looking to advocate against Male Genital Mutilation you can go to Blood Stained Men. I encourage parents to watch the videos on the actual procedure itself and the trauma that is inflicted upon your newborn son. Warning, these videos are graphic and hopefully shows you the trauma your sun will suffer.
The practice of circumcision in the US dates to the early 1900s and was advocated by the scientist John Harvey Kellogg (inventor of the corn flakes) under the mistaken belief that it would prevent masturbation. He also advocated for a little carbolic acid to be placed on the clitoris of female babies. The TV Show, Adam Ruins Everything from 2014 gives a nice overview of the practice
There are botched circumcisions every year, sometimes even resulting in death and the only reason to continue the practice is to funnel money to the medical establishment for an unneeded surgery.
