As a ubm I can tell you that no nonjw's can understand when a loved one joins the jw's either. They must really love the jw to take the time to understand jw-ism and read C of C and other 'apostate' type jw stuff. Of all my family only my (the spouse) family would listen and learn about jw's. I had a friend who came to love a person in a biker group and he was able to leave only while under the watch of law enforcement (not allowed to fraternize with other felons) and we bonded due to the biker group being so similar to jw's. Kind of like blood in blood out mentality (see gangs for reference). In the end he choose the organization over her just like many jw's do. It was surreal when we chatted and the similarities between her loving a true biker (even among law enforcement) and jw's it blew my mind. This all came from someone who was in law enforcement, new the system, etc...
Most non jw's think jw's are just a quirky Christian group which could not be further from the truth. Isn't it odd that after all these years of knocking on door all people really know about jw's is that they don't salute the US flag, no holidays and possibly no blood? after all these years and that is all that is really known by mainstream people.
