Blue, you said:
"I believe the Watchtower Society is so stupid that they think people in the audience will not see through this."
My take on it is a little different. Those who can see through these illustrations are either long gone or, like myself, emotionally long gone. Those that are left will see illustrations as inspired expressions. Thus, the society is still able to find people from the r&f to come on stage and talk about how they are serving god by pioneering etc.
This is part of the "dumbing down" of the message. The only ones that are attracted to the organization are the emotional cripples who will not challenge what is being said.
