Another arrow in your quiver is not feeling it is wrong to lie to those asking the "Do you believe the GB/FDS are Jah's representatives on earth?" or somesuch.
Remember their own definition of a lie is a self serving one that is different from anybody else's definition of a lie.
They say in the January 2016 Public WT under the heading LYING WHAT IS IT?
"Saying something false to someone who is entitled to know the truth."
Use it against them. YOU decide what they are entitled to know and just tell 'em of course you believe the GB is up there with Jah/Jesus. THEY aren't entitled to know the truth anymore than a Gestapo man isn't entitled to know where you hid your Jewish mate.
IMO!
