Hi BU2B, That website might awaken JWs, who are "Spiritually Weak" (still thinking) and probably would not awaken a "Spiritually Strong" (non-thinking) JW. Asking JWs simple questions to understand what motivates them will help a lot to plan how to help them to critically think for themselves.
It depends a lot on why a JW believes in the WTBTS. Does a JW suffer from an incurable disease/disorder/deformity and believes they will be cured after the Big A? Does a JW want to see a loved one in paradise? Does a JW have a close circle of conditional JW friends and family who they are afraid to lose? Does a JW work for a JW boss? What doubts does a JW have about the WTBTS? Has a JW been treated badly by elders and other JWs? Etc.
Helping a JW to critically think for themselves and showing them how much fun they can have away from WTBTS takes time and will probably have a higher success rate than a JW only visiting a website. JWs absolutely trust what the WTBTS writes and the WTBTS writes that a cult must be lead by one man only and not eight, therefore the WTBTS is not a cult.
Even ex-JW apologists after 20 years will say that the WTBTS is not a dangerous cult. I know this because I know someone who said the WTBTS was not a cult to me. I just wasn't quick thinking enough to say, "You are right that they are not a religious cult, but they are a dangerous cult. If you say they are not a dangerous cult without knowing what attributes a dangerous cult has, then you are proving that I am right that the WTBTS is a dangerous cult. If you want to learn more about what a dangerous cult is, please visit www.freedomofmind.com."
Peace be with you and everyone, who you love,
Robert
