Adults have the right to make their own decisions, even if we disagree with those decisions.
Damn right they do. They also have the right to make their own decisions without others deciding for them. If this is happening wihtout their knowledge, like in a cult situation, I think they need to be told about it so they are then able to make their won deecisions with ALL the facts to hand.
You can only give a hand to those who want to leave.
I think thats what I liked so much about Steve Hassans second book, instead of only being able to help people already on their way out he explains how to do 'mini interactions' to get them thinking and kick start them on the process.
