If "most JWs" don't care about 2014, that means SOME JWs DO.
Their growth barely surpasses the birth rate in the developed world NOW. It will only get worse by 2014.
When the "generation overlap" was floated at the 2009 Borg Annual Meeting people said the same sorts of things. JWs don't care about that stuff. Most JWs will let that slide without a second glance.
But this forum has several members that left the Borg BECAUSE OF the overlap doctrine.
If you think 2014 doesn't mean anything to ANY JWs then you're wrong. Some will leave over it. I think the numbers will be at least as significant as 2000.
