Once I let someone on and there are any questions, that person is grilled until either they leave on their own or the group decides they are acceptable. There are Unificationists that are defenders of the faith, there are fence sitters that are interested in the paradox found in Unificationism and wonder what their future holds and there are Post-Unificationists. A Post-Unificationist is what we call someone who has gleaned things from the Divine Principle and True Parents but seeks to go their own way. The most difficult part of being the moderator is to determine when someone has gone completely off and begins abusive monologues against the list. I find all points of view interesting and have found the community spirit of GVI helpful in my Moon quest.
Abusive monologue can come from both sides of the fence.
In my experience on GVI I have seen both abusive defenders of the faith and abusive Post-Unificationists expelled from the list. This means more than a one week vacation. It means the moderator has determined that someone has lost their ability to communicate in a civil manner and is therefore no longer welcome on the list. I guess I could be called a Post-Unificationist. I was married at Madison Square Garden in 1982 after joining in 1974.
