My own experience. . .
I was drawn to the Witnesses by my ex-SIL, who was baptised soon after her marriage. I'm a bit of a nerd and need to work on friendships, so tried my utmost to keep in touch with her.
She in turn sicced the local jws onto me and I "studied" with them for several months. They also seemed to be very nice people, just with a bit of a blind spot concerning the wacky doctrines.
What (apart from said doctrines) kept me away? The repeated attempts to control and to find and exploit a weak spot. In the end, what sort of friend makes the relationship dependant on calling God "Jehovah"?
