When this matter first came up in a previous thread, I mentioned that I wasn't bothered by it because the hand-holding seemed corny and pretentious to me. But I also mentioned that this can be taken and applied as a rule among the more judgmental jws.
Giving this further thought, it is a very worrisome development, because it does open the door to Pharisaic rule-making. The WTS need not say 'you can't' - other jws will take care of that. Those who 'might be stumbled' will take care of it too.
The same thing happens in many other areas of life that should be personal choice. The Society makes a statement on it (such as playing school sports) and the elders and other jws take it to the next level. And that level is virtually always more strict and pharisaic.
