Great thread jp.
I'm so happy that someone of your calibre has this opportunity to assist others in such a forum as that event! It sounds fascinating. I know you will do very well at it.
I guess all the points are very valid. If pushed for time, I feel that highlighting to the audience the point about discovering the "authentic self" is very helpful.
Also, of course, is the need to "give oneself permission to look behind the curtain at the cult's / group's teachings"
Unless someone ALLOWS themselves the PERMISSION to analyse, then all else is a waste of time. They need to "Let go of any GUILT" that comes from doing so.
Highlighting to such ones that it is actually OK and indeed beneficial to question things with a sincere motive is vital.
Highlighting too that there is NO absolutes in all of this. There is no "black or white" "right or wrong" in such a process may also help.
