I think because of people using social media for support when leaving this cult, or any cult, they were raised in there is a danger of moving too fast in changing beliefs.
In '89 when I left it was a matter of finding books in the library or book shops and slowly examining different Bible translations including a non-JW Greek and Hebrew interlinear. Then we bought Bible encyclopaedias and learnt about other religions. Then we started looking at evolution, anthropology and history.
When new people join this site most posters are welcoming and gentle with traumatised JWs who are just waking up. A few react with a knee jerk reaction to any talk about God or the Bible. I don't think it is just because they are atheists I think it's because they're idiots. What do they expect people to say who've had their heads filled with religion for twenty, thirty years or more?
Is this site controlled by atheists? Well Simon is an atheist but there are many religious people here who he's allowed to stay. Perhaps if we all remember it takes time to get free of the cult mindset and not launch at new people who mention God or the Bible. Also it's hard to give up a belief of having someone there to lean on and you're right sometimes these are just young kids who can barely articulate their feelings.
I do wonder what happens when these kids who see TTATT but still believe in God are warmly welcomed by all including atheists then go on another thread and see believers severely criticised for their faith. Does it cancel out their warm welcome? Do they stick around?
