Actually Mary, it's not a "maybe" as to whether or not the kids around here are rebelling, I know they are. When we go for a drink in our local pub, there's often half a dozen or more kids of jws in there, most with elder fathers, and they are smoking, swearing, getting drunk etc, then turning up at the kh for the next meeting. I rather think the double life won't last long, and it'll be the kh that gets given up, not the pub visits. They speak to da'd people (us) as well.
The wts has already lost any authority it had over them, and I doubt it will ever get it back. I'm also pretty sure, from conversations they have about the paries and mightclubs they go to with friends from other kh's, that their conduct is the rule rather than the exception around here, and probably throughout the UK as well.
I smile when I see some of the comments of the apologists on here, pointing out the 1% increase in the UK. Maybe they aren't aware that of how some of their younger members are behaving or of how much they really care about being jws, but they will find out soon enough.
