There are risks involved in neonatal circumcision even without metzitza. Those risks include life-threatening bacterial infection, bacteremia, hemorrhage, surgical trauma and urinary tract infections.
Perhaps these folks should be pressing for government regulation, or even banning, of any neonatal circumcision performed by a non-physician or outside a medical facility.
There are risks to plain circumcision. Certainly the aforementioned risks are reduced when performed in a medical facility (i.e. a hospital) and by a doctor.
How can these people risk their babies health performing it outside a medical facility or by a non-physician?
