If anybody takes action against someone who would
threaten our young ones, and takes action to protect our young ones, it
is Jehovah’s organization. We reject outright such lies.”
In other words, once you decide it's "Jehovah's organization," you are forbidden to consider any evidence to the contrary.
Of course, if you look at evidence BEFORE making up your mind whether it's really "Jehovah's organization," you aren't really interested in the truth and you are persecuting Jehovah's Witnesses, so they will kick the dust off their feet as they cut off further communication with you.
