Sarah,
Why would anyone become so involved emotionally with a JW? If they are not a JW?
I, as a non-JW, can say that it's because of our frame. In that which we know, there's an acceptance of interfaith relationships and other perspectives. That's why I'm suggesting that he attend a couple of your services. He will CRINGE when he hears the things that are said for the words and constructs of a superior denomination are foreign to us.
Non JWs have no idea... if they did, the reception at some doors would go a whole heck of a lot differently.
