“from the article it is not banned. when a male turns 18 they can have this done.”
No problem for someone who isn’t Jewish (well, except for the fact that it is very painful when you’re not an infant, so you’ll need to go under or get a local anaesthetic, each of which have their own risks on top of the risk of the surgery). But Jewish men have a positive obligation to circumcize their sons on the 8th day of life. It can only be postponed (and often is) if the child is having health issues (but it is very rare to go beyond 30 days after birth). So the proposed measure DOES violate religious freedom.
it is assumed there is no pain. Some form of anestesia is used. (wine or a local med shot)
Female circumcision is banned.
