Regardless of that, and assuming that there are major health benefits to circumcision, the Jewish and Muslim communities that practiced it for millennia, couldn't possibly have been aware of any. Because they didn't perform any epidemiological studies measuring rates of penile cancer and HIV infections. But they must have noticed a lot of babies and boys getting fevers and dying from infections shortly after the procedure was performed on them. Clearly, the rite lived on because "God told them to" despite the adversarial effects it had on their children's health.
And I'm not especially impressed by that article you linked, either. Several of the sources it cites in support of its arguments, when examined, turn out to be tangentially related at best, and not at all supportive of the claims to which they're linked.
It’s my opinion that circumcision acceptance is based on a cultural/ideological blind spot.
