there were other aspects of the study that bothered me as well. i can't quote it precisely since i dont have it here with me, but one part talked of the son leaving because he prefers "the temporary enjoyment of sin, over a relationship with jehovah and his parents". that short statement had me disagreeing in three ways.
1- it is meant to fool witnesses who dont know any better, that the only reason young ones ever leave the org is because they want to party their asses off and live a 'worldly' lifestyle. though it's true for some, there's no mention of all those who leave because of doctrinal or historical reasons, thereby not calling to mind the validity of such reasons, and creating the illusion that all those leaving are wrong in doing so.
2- saying they prefer it over a relationship with jehovah. if they have independantly come to the conclusion that there is no jehovah or god at all, then prefering a relationship with him isn't even a factor.
3- of course nearly all WOULD like to keep a relationship with their parents, but they realize that keeping that relationship comes at the cost of living a lie, pretending to believe in things they no longer believe in.
