Leaving a cult includes learning other opinions and how they have been arrived at. Learning to learn. Honestly, I pity someone attempting to start over. The internet is a wonderful repository of religious information, most of which is objectively wrong, but don't think it is our role to screen out the noise. That starts to sound like censorship. I feel our role is to assist sorting it out by encouraging critical thinking.
I'm sure many have the view that my critical research is offensive, even harmful. So far no one has asked me to leave but I can imagine it has been considered. I have valued the input of others with contrary views, it has pulled me back from the fringe a few times. lol.
Discussion boards are different than other formats like Reddit. There is supposed to be an exchange, and reasoning and that means sometimes topics get mired down. That's not a problem, it's a reflection of how scholarship works. If a topic reaches an impasse, that suggests a new approach is necessary.
The bottom line is always, civility.
ps. I'll also add that mental health must be a factor. Someone with the opinion that angels/demons exist is one thing but someone who talks to them is another.
