There are a number of reasons why it may be done.
Obviously any medical reason is important.

However, it does have a faith element.
It's not for me not being of the Muslim or Jewish faith to condemn the rite.

It is a vital part of those religions and while it may seem bizarre to those of no faith.
To those religions it's very important.

So I'd rather respect those religions rites myself.
They believe it's part of a covenant.
A matter of deep faith.
