OrphanCrow is right. It has to do with the fundamental question: "Who am I?"
Most Witnesses were devoid of their own unique identity and compressed into a mold, the WTS mold. When asked the question "who are you?", they have little more to say about their identity than: "I'm a Jehovah's Witness". Therefore, they don't know how to go on about their life without that fundamental framework:
What friends will they have outside the Organization?
What will they talk about outside the Organization?
How will they fill their time outside the Organization?
What hope for the future will they have outside the Organization?
What purpose life has outside the Organizaion?
This is a huge chasm to contemplate. So they rather rationalize away the current changes within the Organization and swallow whatever spin the Governing Body puts on it.
