Disagree with the premise though. Being shunned for being a sloth or emotional drain or con-man or thief or murderer makes some kind of social sense; being shunned for religious beliefs is unnatural and feels wrong. Can never like it
That's true.
It took me finding out they were a cult before I realized that shunning a person because they no longer hold the same religious beliefs as you was abnormal. And it's funny when I watch some TV show like 48 hours, and some criminal who's been convicted of some awful crime will still have family and/or friends who will stick by him and love him. Yet if I reject a religion, all of the sudden I'm a person not fit to speak to. I think your average JW is so indoctrinated into the cult that they cannot understand the absurdity of rejecting a loved one just because they no longer want to be a JW.
