Desirous and Amelia, you are correct in that very few "outsiders" have any idea what the JW's believe other than the ones you mentioned. I have caused two fellow co-workers here to stop their studies after I gave them a brief history on the org and what they could expect in the future.
One lady said "You mean they will expect me to believe that God chose them as the only true Christians in 1919? They have never mentioned that." When she did later ask her study guide if that was the case, after a long dance and moonwalk, he admitted to it.
She replied "Well as of 2012 my brain has chosen me to end this study. Thank you and good evening."
