What are the excuses of a sincere doubtful JW to not discover anything about the JW. org?
I really doubt that much more effort of Internet exposition need to be made.
I think the people inside the Watchtower now is made by more than 90 percent of people who WANTS to be a JW. True believers who knows the TTATT.
I left in 2006 and one thing that shocked me at the time was to discover people who had read the CoC and decided to remain a JW. I think this is already the main reality among them.
This new generation was born connected in the Internet and they know about the TTATT. Maybe some of them are just waiting to be financially independent to get out.
In the end it's not about facts and truth. It's about individual choice and some will always chose odd things.
