I also find this an interesting comment:
Surely there is ample evidence to show that you can trust the channel that Jehovah has used for nearly a hundred years now to lead us in the way of the truth
Why did they say "nearly a hundred years", when Russell started the movement nearly 150 years ago? I guess it's because of their new "faithful slave" teaching that claims the slave same into existence in 1919 or something like that, and only includes the "governing body", not anointed JWs in general. They say we should trust them because they claim to have been the slave for a hundred years. A more relevant question might be: why trust a "slave" that only figured out who it was and when it came into existence a couple of years ago, and was apparently wrong about its own identity for most of its so-called period of tenure.
