This is exactly the point.
It is an exercise in futility to try and blind the R&F with pseudo intellectual "scholarly" works any more and they know it. So much can be debunked. They are hanging onto 607 and 1914 by the fingertips at the moment but being hit not only by the amount of evidence for their dates being 20 years out but also the fact that bugger all has happened in 100 years.
The amount of info debunking large amount of WT doctrine (especially JWFacts) allows anyone who can their mind past the cultural firewall of anti-apostate rhetoric to fully examine the history of why JWs preach what they preach now and see it's a procession of failed prophesy.
The only way now is through emotion and making the R&F care less and less about doing any research at all. The more top down the meetings become, with spoon fed presentations and streamed talks from Command Central the less and less chance there is of R&F members even caring about doing any research.
