Those videos open up a tremendous amount of discussion opportunities.
Its completely whitewashed garbage - if you do just a brief search on the board, watch them on Youtube and take notes, you could have lots of opportunity to get her to think. You are in the enviable postion of being able to ask whatever you want about the religion and do the hardcore examiniation of it that JW's are not able to do, based on being conditioned that way.
You might be able to play it as "Hey, I'll watch the videos and write down some points I found interesting".........
If Russell founded the faith, why are his teachings no longer taught? Where did Russell get his dates from? If Russell was teaching "truth", why would a JW be disfellowshipped for teaching those things today? ........Or, even better when it comes to Rutherford - you could have a field day. They present him in those videos as a fiery champion of truth, when in fact he was a power hungry nut whose writings were so full of incoherent babble - no JW i know has read "the Finished Mystery".....you should check it out, since in the video its presented as a expose on religion and government that shook the world to its core! The reality? You have to read it to believe it!!!
It sounds like she is interested in you. For a single JW woman to stop by your house "unchaperoned"....that is definitely walking the fine line. Not to sound corny, but if love does develop, it can cut through the BS of the Watchtower. Yes, there may be bumps in the road, but you can say that about any relationship these days, regardless of religious beliefs. Who knows, maybe she is at a spiritual crossroad in her life, and wants out of the circus, but is just doing what she has been trained to do.........its hard to crawl inside the mind and motives of a JW, as they are deeply influenced by the organization and its dictates.
Best wishes for whatever you decide!
