Very interesting story. I think it depends on how seriously individuals believe what the GB say.
My own mother used the words 'I have to remain loyal to Jehovah' when I said what would she do if I ever chose to 'officially' leave the organisation; and know full well she would shun me. I remember sighing when I heard her say that.
I felt like saying what on earth did you get me into all those years back when I was a young gullible teenager.
