I agree that many posters are bitter - and from my reading of some (but by no means not all) of the PMs I have received , some are very angry towards existing JWs.
I think it is nt good to feel bitter to individual JW's that you do not know. Of course peolpe can feel very angry to some JW's, who did bad things to them. I see individual JW more as misquided victims.
(I never got a lot of PM's though.)
(By the way , my Mum & Dad were married when I was conceived!)
So were mine, but what has it got to do with it?
I suspect that JWD posters are a "hard core" of former JWs who still take an interest in JW matters composed of a loose grouping of classic "apostate nutcase" types , many who still have family & friends in the organisation and some who feel they have found friendship and companionship (albeit via an electronic medium) with others. According to the UK map on this website, only about 30 or so Brits post compared to many thousands who have left the Truth in this country , so you are talking about a select group of people.Well, it depends on what people have experienced. I think there are all kind of posters. Some non JW's also.
If you do a search on the net , you will find ex-Catholic , Mormon , Anglican and numerous other message board websites and the attitude and bitterness is very similar.probably.
