There is a saying in medical ethics that can initially appear trite, but which is of great importance.
Good ethics depends on good facts and good law depends on good ethics.
The medical facts about infant male circumcision have changed, especially as a result of carefully undertaken medical research. Routine infant male circumcision is harmful in itself and has harmful consequences. These harms are not outweighed by compensating medical benefits, when the procedure is not medically necessary. I have spoken and written elsewhere on the topic of pain and pain-relief treatment. I believe that there is a fundamental human right not to have pain intentionally inflicted on one's self, and where pain is unavoidable, to have fully adequate treatment for the relief of that pain.
