Apparently San Francisco doesn’t believe in the First Amendment’s right to free exercise of one’s religion, a right to privacy or choice.
Circumcision is an open-and-shut First Amendment right (”free exercise”) for observant Jews. “Free exercise” does not protect the right to conduct human sacrifices (or even to deny life-saving treatment to minor children of Christian Scientists), but supposed harm from infant circumcision is conjectural “junk science.”
Some would claim that if the First Amendment protects infant circumcision, it should also protect female genital mutilation (sometimes misleadingly euphemized as “female circumcision”). In answer:
(1) Female genital mutilation causes a lifetime of significant medical harm.
(a) but I wouldn’t object to a reduced procedure that left a small harmless scar.
(2) Female genital mutilation is a folk tradition in some cultures, rather than a requirement of a recognized religion like Islam.
