GONE FOR GOOD:
If the purpose of this letter is to prevent a JW from being shunned by other JWs in the congregation, I do not believe it will work - regardless of what any JW or soon to be ex-JW says about their so-called status as a believer, non-believer or whatever.
Maybe in their files it will say you stated you were no longer a JW on such and such a date (for legal purposes), but this will not prevent you from being shunned.The plain fact is that nobody can force people to talk to them or associate with them. And we all know what they are like with shunning and judgmentalism - even with people active in the religion. If somebody were to submit a letter like this - they have no idea what’s being said about them and what it will be perceived to be in the JWs who hear about it.
If I submitted such a letter and afterwards were in a store - and my former JW friends ignore me when I say hello..if I ran after them waving the letter in my hand saying in a loud voice what it states..will that compel these JWs to change their attitude towards me?? I doubt it.
