How graphically this example illustrates how ill-equipped JWs are to defend their faith when challenged by anyone in possession of a few facts about their beliefs and history, and how vulnerable they are to being ``blindsided" by a barrage of evidence they never knew existed and that nobody--least of all their elders-- warned them to be prepared for!
It's ignorance of such facts -- both of the public and of the naive dubbies they send to the doors -- is the only way left for the WTBTS to make any headway; disclosure is Enemy No. 1.
