At times what a Jehovah's Witness may state when facts about the organization's past are brought to the forefront include:
"You are so focused on the past that you can't see the blessings in front of your eyes."
Without even approaching or deconstructing "the blessings" aspect, there are major issues with the reasonableness of such a claim or others similar to it.
The entire religion constantly refers to the past in both the Watchtower Study and as examples for them. What the comment is really implying is to stop looking at a specific issue or better yet, anything negative about the organization from the past.
So how far back should we look? What are the start and end points of where reflection in the past about the organization is appropriate? Which things do we include or leave out?
Would not an honest look and objective view include their entire past and all things both pro and con Jehovah's Witnesses?
Additionally, ask how that comment is not applicable to any other religious organization. Cannot any member of any religion make the same exact statement? It does not make that religion any better or 'truer' than another.
It is selective attention to the past or-and living in an Orwellian world. If trying to reason with an individual with a selective past focus, you are going to have a hard (and probably wasted) time doing so.
In fact, it may be better to keep in mind this biblical directive in reference to such an attitude and mindset:
"Give not that which is holy unto the dogs, neither cast your pearls before swine..."
