Hi Mulan: Good question. There are about 80 to 100 million Catholics in the USA. [Correction: according to the National Council of Churches the number of US Catholics is 62,391,484 (41.29 percent of total USA church membership]. The Catholic Church itself is much more accountable to members than the WTS is to JWs. Many Catholics are the ones who sued the church until it reformed its policies.
I believe that the onslaught of lawsuits coupled with the Dateline program will at least force the Watch Tower religion to reform is policy of shielding JW pedophiles. That is the primary and central goal of all who have been working on this project.
I doubt that JWs will leave in any great number, as most will incline to believe the WTS spin on this, and choose to remain - for the near term anyway. But, if the viewing public pays much attention, along with the almost certain level of follow-up radio and TV talk shows and discussions among many non-JWs, it will eventually play itself out at the doors when JW call, and among JWs who attempt to informally witness to friends and work associates.
The resulting decline and interest in the JWs, will slow new growth even more than it is now, and they will be confined to holding on to young JW children as their future. But, if they continue with the present ways they manipulate JW children, then in time, the organization will shrink with respect to its ratios to the rest of the world.
Time will tell. - Amazing
