“Oh yea then there is the female mutilation like they ordered in Iraq the other day.But you are okay with the Jewish mutilation of men??”
False equivalency. Circumcision, like kosher laws, were promoted for health issues. At the time, no one knew about trichinosis, or how to properly prepare pork or ocean-based scavengers like shellfish. Didn’t work, though: the Jews didn’t get sick, and therefore, they must be witches, therefore tortured and put to death.
Female genital mutilation is part of the concept that sex can be for only one purpose: procreation, and therefore women should not enjoy it. Not only does female genital mutilation prevent enjoyment, it often promotes pain during intercourse.
Now that we understand health better, circumcision is not as necessary, but—like many religions—tradition trumps practicality.
