Hi metatron,
It's a real joke - and a sad one at that. Even Jesus - used repeatedly by the Society as an example for all to follow - didn't get baptized until well after he reached adulthood.
For any lurkers who don't know much about JWs, this is how it works:
1. One can't be disfellowshipped (excommunicated) unless he/she is a baptized baptized member.
2. The threat of disfellowshipping is a very powerful tool the Society uses to keep members from straying. Remember, JWs live in a very closed environment - most don't have any friends outside of the organization - so to be shunned by the only people you know is something to be avoided at all costs.
3. So if the Society can get members to become baptized at an early age, they pretty much - in most cases - have them for life. And that translates into MONEY for the organization, since the member is going to buy a copy of everything the Society puts to print - books, magazines, every latest edition of the New World Translation (the Society's version of the Bible) etc. Not to mention the amount of money in the way of donations this member will contribute during the course of his/her life.
It's all about money, money, money....
