Rabbi Aharon Teitelbaum compares the "attack" on metzitzah b'peh (MBP), the direct mouth-to-bloody-penis sucking done by hasidic mohels to babies, to the Spanish Inquisition and the Holocaust. And what is that "attack"? Publishing scientific data on MBP's risk to babies – it sometimes kills them – and requiring parents to sign an informed consent form before the procedure can legally take place.
