cwald, I think all they can do are two things, basically:
1) Not claim visits when they don’t happen – and I think they are doing that in spades. In fact, there are some critics who complain that they aren’t true prophets unless they say that, but they still don’t.
2) Claim visits don’t happen – and I’m not sure they don’t.
So, in regards to that one issue, I really do think they are doing about as much as they can – especially since I have heard two of the currently living and recently deceased apostles talk very openly about how they receive revelation / inspiration, and visits were the furthest thing possible from those descriptions.
I also agree it’s time to move to #2, so I will close this thread and open a new one on that topic.
