While I can't unfortunately add to you list, slim, it is very telling set of numbers.
To me, it seems rather evident that all the Governing Body members (and past Presidents) were true believers. Well true enough to make for themselves a social contract, where they traded having children for their positions in Bethel.
But fact most were childless, only goes to illustrate why the Organization has a real lack of understanding of problems of child rearing, teenagers in particular. For the constant repetition of 'prayer, bible study, field service and meeting attendance' as the solution to any problem a youth has, is clear proof that none of them have a real clue of the world around them.
Similar too is the Governing Body's strong recommendation of singleness and childlessness (done through to drive for young couples to serve full time), is really done only because they have never experienced the joys of being a parent themselves.
Would the Society look different though, if the Governing Body had normal families and kids? Undoubtedly ... a lot more humanist, I wager. Which is a pity.
Thanks for the original post.
