My PseudoAunt used to read and very infrequently post at exmormon.org. She's not an exmormon, but she found it useful at times to have a place to be among like-minded individuals while she attended BYU as an undergrad and law school student, and she didn't say this, but she probably also had a desire to vent regarding inlaws that are almost entirely practicing Mormons. She stopped going anywhere near the website because she found it to be very snobbish. She felt that when she commented on a thread, her comments were totally ignored, and when she asked a question, that, too, was ignored.
My PseudoAunt is hypersensitive at times, so all of us took her account of the supposed snobbishness of the exmormon.org message board with about two tablespoons of salt. My PseudoUncle even went so far as to post on the exmormon.org message board himself, airing his wife's thoughts and asking what the story was. He was relatively warmly-received and was assured the board was not cliquish or snobby.
I had a question relative to domestic help in the Romney household that could possibly be answered by a Mormon. Mormons tend to know Mormons who know other Mormons, etc., so that there's typically a very finite number of degrees separating a given Mormon from a celebrity Mormon. I introduced myself in my post, which was one of the things other posters recommended to my PseudoUncle that my Pseudoaunt do. I was polite and not overly wordy. I wrote just enough to explain what I wanted to know, why I wanted to know it, and why I thought the exmormon.org message board might be a decent source for the information I was seeking.
My message was unilaterally ignored when I posted it. I posted a reply reply to my own thread to move it to the top again. It was then ignored again until the thread was removed by the moderator.
PseudoAunt, I take my words back. You were not paranoid. The posters at exmormon.org really do behave snobbishly and cliquishly.
If anyone thinks it might just be my age that is a problem to the regulars there (I'm a regular reader, just not a regular poster; PseudoAunt read regularly for several years before ever posting anything) a vapid poster there who calls herself Chelseamarie and who supposedly just turned sixteen quite regularly posts nonsense that receives responses.
If you have concerns with separating from LDS Inc. and need a support group, I wouldn't recommend exmormon.org as a source of support unless you have really thick skin. Ss a group, they appear to be about as cliquish as Mormons are.
