The brainwashing is very strong. You can see people thinking- "there's something that just doesnt make sense here"- but then they are snapped back by the incessent droning- "You have the truth, this is the best way of life, the GB or F&DS are God's instrument, must believe, might be changes, dont be weak....." etc, etc, etc
But there are moments when you can see clarity on their faces. If only they would have the courage to ask the questions that lurk in the back of their minds.
That is the only path to freedom.
