The commandment in the Torah to circumcise every Jewish male on the eighth day of his life is so sacrosanct that every branch of Judaism observes the practice. Circumcising your son is the very least you do to be identified as a Jew in the Jewish community. On the eighth day of your son's life, close your eyes and think of Israel. For your parent's sake, if not for your son's. You will have the rest of your life to debate the medical and cultural pros and cons of your decision.
Positions change, as common sense dictates.
If there were no discussions, there'd be no Talmud. Everything deserves re-examination with time. In France, Jewish babies are circumcised symbolically only. Arab or African tribal mothers subjecting their daughters to clitoridectomies justify the brutality of the procedure by insisting their girls will be ostracized from the community. Circumcision is genital mutilation and brings pain to a part of the body we should only associate with pleasure.
