I don't think references to Steven Unthank as a "lunatic" are terribly helpful. The experiences we've all gone through as victims of a religious cult prompt us to deal with it in different ways. He clearly has a lot of anger bottled up over what he sees as injustices and he is grasping at anything to resolve it. I agree that a much simpler submission to the court of just a page or two dealing with the specific issue would have been better (and accepting that no Victorian court is in a position to right the wrongs of the past in his life), but it's his action, not mine.
I personally don't see that there's much to be gained by his appearing as a sideshow on Rick Fearon's circus; I fear that in trying to use that medium of publicity he is simply going to be used himself, but again that's his call, not mine.
In a way we're all troubled souls, all damaged goods to a degree and we gain support from one another by being here. I wish Steven well, and I wish people would back off in their denigration and ridicule of him.
