The growing anti-Semitic images and caricatures associated with the attempt to ban circumcision in San Francisco are disturbing. These include the highly inflammatory "Foreskin Man" comic, depicting a superhero saving innocent boys from evil circumcisers, which the Jerusalem Post reported to have been produced by Matthew Hess, "one of the central backers of the anti-circumcision measures." Indeed, the attempt to ban circumcision in San Francisco smacks of a nefarious campaign on the part of the ban's organizers to portray circumcision as genital mutilation that gives the lie that Judaism and Jewish practice would ever harm a child. I debated Lloyd Schofield, the main man behind the ban, on CNN. I later respectfully asked him to debate me in public where we would have more time and, after he penned a friendly email which curiously implied that there is not much difference between our two positions, he suddenly declined.

But if the case against circumcision is so clear-cut, and it is a grievous assault on a harmless infant, then why decline the debate? Perhaps it is because the organizers know that in any debate their attempt to correlate the excising of the male foreskin with the removal of the female clitoris -- a point they have repeatedly made -- will be shown up to be a malicious and absurd lie. Female circumcision is all about removing a woman's ability to have pleasure during sexual relations and is a barbarous act of mutilation that has no corollary to its male counterpart. In my book Kosher Sex I demonstrated conclusively that Judaism celebrates the sexual, intimate, and erotic bond between husband and wife and the attempts to malign circumcision as a method of denying a man's sexual pleasure are ignorant and biased.

San Francisco is supposed to be the city of live-and-let-live even as it now betrays a curious attachment to the male foreskin, with its ludicrous attempt to punish its large Jewish community with a fine of up to $1,000 or up to one year in jail for simply honoring the oldest of all Jewish practices and rituals.

When I lived in Western Europe for 11 years it was common to hear attacks on circumcision and shechita coming together, as if there was some correlation between the humane slaughtering of an animal with the cutting of a child's foreskin. Sweden has a reputation of being a pretty laid-back nation but it stiffens in the face of circumcision. In 2001 when it enacted a draconian law requiring a medical doctor or an anesthesia nurse to accompany a registered circumciser and for an anesthetic to be applied to a baby beforehand. Swedish Jews and Muslim banded together to object and the World Jewish Congress condemned the law as "the first legal restriction on Jewish religious practice in Europe since the Nazi era."

All this, of course, belies the medical facts. Circumcision has been proven as the second most effective means -- after a condom -- to stop the transmission of HIV-AIDS, with the British Medical Journal reporting that circumcised men are 8 times less likely to contract the infection. Circumcision removes Langerhans cells in the foreskin with special receptors that may grant the virus access into the body.

Circumcision also significantly reduces the transmission of other STD's like genital herpes and syphilis and also reduces the risk of urinary-tract infection, and men who are circumcised have 100 percent immunity from contracting penile cancer.

Male circumcision is much healthier for women, significantly reducing the risk of cervical cancer by at least twenty percent according to an article in the British Medical Journal in April 2002. Cancer of the cervix in women is due to the Human Papilloma Virus which can thrive under and on the foreskin from where it can be transmitted during intercourse.

So why the effort to ban circumcision? Simple. Radical secularists for whom Judaism is a target of choice wish to portray religion as so barbarous that it excises any pleasure in sex, reducing copulation to a cold and sterile act of baby-making.

The lie that religion frowns on sexual pleasure is widespread. In fact, deeply fulfilling, ecstatic, and climactic sex is a must in Jewish law which makes it a sin for a man to have sex with his wife without pleasuring her first. Judaism insists that sex be accompanied by exhilaration and pleasure as a bonding experience that leads to emotional connection and intimacy.

Indeed, we Jews could teach even the highly sexually adventurous people of the Golden Gate City a thing or two about great sex, the proof of which is that we alone, among all the nations of the world, are still here after thousands of years, due to the fact that our circumcised ancestors were pretty good at doing it.

Had Messrs. Schofield and Hess canvassed Jewish husbands and wives before they got the attempted circumcision ban on the ballot, they would have discovered that we Jews are doing just fine in the sexual department and could really do without their bothersome assault on our ancient rituals and the privacy of our sexual connection. Circumcised Jewish men are great lovers and I would strongly advise Schofield and Hess to keep their nose in their own business and maybe even read my other two books The Kosher Sutra and Kosher Adultery to receive some great Jewish advice for take-me-to-the-moon-and-back sex which might rescue them from their own repression that necessitates their peering into other people's bedrooms.
