I don’t understand your last paragraph. What do you mean “must be cemented to who they are”? What do you mean when you say “the problem is not the faith, but their relation with it”?
What was not cemented in you when you left the Mormon Faith? What was the problem you had with your relationship with your Mormon Faith?
The above are not “gotcha” questions. I am trying to understand your meaning and a bit of your conversion history in relation to the title of this thread.
It is an ancilary position to this thread. People are pulled from this faith and pulled

IT AS WELL.
I believe that it is extremely rare that devout people are pulled by another person’s efforts to leave their original faith and convert to another. (I am not talking here about predatory cults but standard conversion from one religion to another.)
With me it was not a position of being devouted to my faith, but the lame beliefs and wierd things that are believed that are never spoken of outside a group of other Mormons. Then there are the beliefs and practices that are had that are never spoken of outside of the temples. I was devout untill I got into the wierd things that are believed. Then my brain kicked in and said “Nope, this is abnormal” and I left.
As a Mormon, did you every pull someone who was devout away from their religion when you were on your mission?
