The question I always have about this sort of talk....
What if the "negative information" comes from a non-apostate source?
They create this near-hysterical revulsion toward "apostates", then conflate the idea of "apostasy" with "presenting any information that reveals the organization saying or doing something that is wrong or harmful" regardless of source.
So, the argument becomes "negative information is, by definition, apostate information. If you hear negative information about us, it is always false and it always comes from apostates."
That is wrong. The really evil part is that they know it is wrong, yet they say it anyway.
Every time I am inclined to give them "the benefit of the doubt" on the question of "are they evil or just deluded", they come out with a talk or article like this which answers the question in full.
