You are aware that JWs consistently number far higher in national censuses compared with their own statistics? This is in contrast with other religious groups.
I have 2 childhood friends who haven't been in a Kingdom Hall for a few years. They have a beard (since when it was prohibited), long hair, participate in lottery cakes in our friends group, and they date or marry worldly women. In our group of friends, when me and my brother (also POMO like me) mock JW teachings or new lights, they are the first to defend WT. But they don't plan on returning to KH anytime soon. This is probably the type of "JW" who self-declares on the census. If WT depends on them to survive, it is in trouble. :-)
I joke with them saying that if they want to go back to KH, it's better they do it soon while there are KH in the city!!!
