So cutting off what part of a female's junk is equivalent to circumcising a male? If you find the comparison too disparate, what would bring it closer to balance? (And I submit that neither you nor I have any real knowledge why female circumcision is carried out, except for the fact that it is almost exclusively female-on-female and not something men do to women. I am completely over westerners exclaiming, "it's done to destroy pleasure!" "for chastity!" "to make childbirth impossible!"). I have worked with intersex, FGC and MGC issues for decades, and I never cease to be amazed by the reasons that Americans insist FGC is done.
Or is your argument that guys are just born with useless, expendable sex parts and females are not?
The point of the ethics discussion taking place about circumcision in several countries is not primarily about who enjoys sex more. It is about whether a human being has the inherent right to know and enjoy his or her complete sex organs in particular, and body in general. It's not your place or mine to say to someone else that half the skin of his penis is not worth knowing or enjoying. [Infant circumcision removes on average 51% of the skin system of the penis, British Journal of Urology 1996.] There is also an appearance issue; some males deeply resent having their glans permanently "revealed" without a medical reason, and are ashamed or disappointed to have a scar on their penis. This can inhibit sexual relations or undressing/showering around others. Some uncut guys are self-conscious too, but (a) their bodies are anatomically correct and their beef is with Mother Nature and (b) they can easily do something about it, like retract or get cut. These same inhibitions can lead people to demur when asked by friends or a professor about their circumcision status.
FFS, why do so many people go straight to the "I like it so it must be OK" argument?
