I read about this in Christopher Hitchens' book God Is Not Great (How Religion Poisons Everything) several years ago. I'm appalled that this practice has been allowed to continue, and that the offending Rabbi has not been reported to the Department of Public Health for wilfully transmitting an STI or arrested for endangering the health of newborns and child sexual abuse.
What pissed me off was the decision that the parents' and Rabbis' "freedom of religion" trumped the children's right to not be sexually abused or have a potentially fatal disease transmitted to them.
