Brainwashing may be too harsh of a term....It's more a conditioning process, especially for those who are raised a jw. After being bottle-fed with wts doctrine, we read the Bible with 'wts glasses' on. The wts has made it very difficult for removal of these 'glasses' through the shunning policy and the overall fear of wts teachings..(eg. death at armageddon, etc.).
I myself, do not have any family in the wts. I began studying at age 18. After 20+ years of 'fence sitting' (I was never baptised as a jw), I chose to get to the bottom of my own procrastination. I started reading the Bible without any so-called aids of the wts, taking a fresh look at the scriptures. My goal was to have a personal relationship with God, irregardless of what that meant. And, my spiritual growth began to take the drivers seat. I have never looked back....only forward.
For those who have family in, looking and holding back would be a natural reaction. It would be very difficult to leave the 'pack'. It's similar to being raised with abuse...it's the only life they know. Leaving is not really an option.....for they question, 'where would they go'? The conditioning has left them dependent upon the wts for thier basic needs of family, structure, acceptance, and the purpose of life, (no matter how dysfuctional in reality). Just some additional thoughts....
