Thanks for the experience wobble. I've been in three different congregations during my time as a witness (two of them in the UK) and I firmly believe that each and every congregation of JWs keeps a healthy stock of certifiable nut jobs. It always struck me, even when I was relatively firm in the faith, that such people were more of a hindrance to the "good news" than a help. If two people turn up at your door who are smelly, strangely dressed, and just plain weird, this reflects on the organization they supposedly represent, and you immediately switch off to anything they have to say, unless you are bonkers yourself.
The simple fact is, the organization is like a magnet for people who are 'a penny short of a pound', because where else can an insane person go and have instant "friends" (just add water, i.e. baptism) than their local kingdom hall? When you're a Witness, your fellow Witnesses are more-or-less FORCED to be friends with you, even if you are not normally the kind of person they would choose to strike up a friendship with (because perhaps you're a looney and have poor bodily hygeine). If you're slightly bonkers, it's a win-win scenario, however warped the teachings of the Society may be.
I hope the barmy army continue to frequent the streets of Britain and other countries. Ducking in and out of charity shops, picking up curious things from the pavement, wearing strange ensembles of outfits - they are a living testimony to the mental fragility of the organization they represent.
