"Those who simply leave the faith are not shunned"
I propose that JWs who wish to leave send the following letter, along with the downloaded page directly from the WT website (the one that contains it) to their friends and family first (while they are still active), then to the society.
Dear brothers,
I do not wish to officially disassociate myself from Jehovahs-Witness and thus be shunned.
I simply wish to as the Watchtower website says "simply leave the faith."
Since I wish to "leave the faith" now voluntarily there is no grounds to "disfellowship" me as I am no longer of the same fellowship.
Also since "Those who simply leave the faith are not shunned" I expect to contine our warm friendship and family ties on a personal level,
Love, Mr. John Doe
