Interesting about the sales meetings and pitches... This is one of things which helped wake me up (the biggest thing which finally woke me up was that evil publication, My Book of Bible Stories, which I almost gave to my little grandchildren, when I suddenly and thankfully, saw those awful, nightmarish pictures through their little eyes!)
But getting back to the sales meeting thing -- my husband and I were (very briefly) involved in an MLM and the similarities between their meetings and the JW meetings were astounding. All you had to do was change the product.
Sales pitches, testimonials, hyped up information, exclusive special sales force people and levels.... and the whole way-of-life thinking, taking every opportunity to share your message / product with everyone you meet.... keeping records, noting personal preferences or objects of people to use as part of your sales pitch.... the big wigs at the top.... the pressure to advance and do more, more more.... The tendency to look down on outsiders for not having the same wonderful, superior experience (or product) ...
