I gave it to my elderly mother a few years back and encouraged her to read it. Like many devout JW's, she took it and started reading it with the attitude that she could pick anything this guy says apart and use it to prove the JW's ARE right!
She was reading it with a "pish-posh" attitude, I believe reading over it without actually thinking about what it says. Up until she got to a certain part. I truly believe it was the part about the double standards, Mexico vs Mozambique. She shut it down, then and there, would not read any further and wanted that book OUT OF HER HOUSE!!!
Her exact words, "I don't care, I am sticking with the organization!" It obviously struck a nerve. Like many JW's, she prefers to belong to an organization that will do her thinking for her rather than use her own mind.
It has been my experience that unless a JW already has some doubts, it does little good to try to get them to read CoC, or any other book that exposes the WT.
