The story certainly shows the cruel side of the JW religion, and especially how members are programmed to do whatever the society ask.
Unfortunately, many times the article it speaks about members having to sell books.
Now we now know that they do not sell books. Most times literature is taken and offered to a householder, and if they respond they may be asked if they would like to donate. However most times these days , the witness takes care of the expense, so it is wrong to say members sell books or magazines.
The article would have been good to show a witness had it not been for that. As it is because of the false statement about selling, no witness would listen or learn from it. When speaking to witnesses you need to have every fact correct, if not they will jump on it and reject all the other true points that have been made.
