Logan, I think you made some excellent observations though I believe that the reasons people come here are as many and varied as their stories. I think this forum is like anything else, some people may stay a short while, while others might never leave and as long as its not unhealthy that's fine. I think for many this place is sort of like a VFW post, where people with a shared experience can sit around and socialize and feel comfortable because of that shared experience. They can rant about the WBTS it if they want or talk about something completely unrelated, but there is always that underlying common experience tying them together. Taking a break once in a while, good advice regarding just about anything, work, school, etc. I also agree that if coming to this site is keeping a person from moving on in their life, then possibly it isn't healthy for them and they should eliminate it. From what I have seen in my couple of months here most have moved on with their lives, but find some value in posting here for whatever reasons. It seems very common as well with many support groups that people that have gone through the process often become counselors or volunteers to help others and there is obvious value to that.
As for treating others the way you would like to be treated, excellent advice. I have done that with my family which are mostly still JW's, but I find that they are not nearly as tolerant when I mention what I did over the holidays as they expect me to be when they talk about going to assemblies or make derogatory comments about other faiths or individuals. Just my experience there.
