Questioning your motive for doing research is easier than defending the results of the research. It's a diversionary tactic, and they'll try to use it to discredit you and, by extension, your research.
Finally-Free, that's an excellent point.
Drew, good points about dubs being conditioned to accept information without a lot of verification or proof other than the WT saying it's from the Bible. It can be difficult to try to break someone from that attitude when they're used to being rewarded instead of questioned.
LWT, good question: Is it best that we just blindly follow what the Society says?
With my friend I would probably ask first, "Is it good to blindly believe anything were told?" and if they answered in the obvious "Of course not", I would follow with, "is it good to blindly believe whatever the Society tells us?" and see if it creates a short circuit.
