That is the bottom line for a Witness. I have tried so many times to reason with Witnesses, and they react the same as I did almost all my life. The only success I am having is hopefully planting some seeds, because that worked with me, over a period of time.
Many threads on here describe reasonings and great points designed to "wake up" Witnesses. It seems to me that is a slow process, because even if you are right about a certain point, here's the Witness standard answers:
"Well, that may be true, perhaps, but anyway, its still the truth because
We don't go to war
We have worldwide unity
We have the Faithful Slave
We preach all over the world as Jesus taught
Plus, we need to wait on Jehovah
Where else would we go away to?
JW's are conditioned to answer this way, so it takes time to get through. I am trying my hardest to get some to reason, but its not easy at all.
I think little by little we can do it, and then the whole thing will crash.
My hope, anyway.
