StarTekAngel I like your OP. I think it's natural for people to get annoyed and frustrated at beliefs that are very similar to the beliefs that ruined their lives. Who wouldn't!
It's the debaters that bore me, playing word games rather than engaging with the content of posts but I think it might be because everyone has their 'subject' don't they?
Whether it's biology, physics, computing, theology. They are well versed in that subject but if someone introduces something they don't know about they can resort to less than respectful tactics to divert attention from their lack of knowledge.
I like all your analogies about real life because although this is a forum where people often debate religion it's also where people come to in recovery from a cult. These are real life experiences that these people are bringing, with huge amounts of pain. I wouldn't want them to be put off this place of refuge from the cult. I think it's probably a good idea to keep beliefs to yourself however, if you can't prove them. Why cause yourself the stress of ridicule.
As for those who ridicule beliefs, as I said it's totally understandable given what beliefs have done to all our lives.
Personally I don't ridicule but I don't accept anything that anyone says at face value.
