I guess I was wondering if the vitriol is because she claims an apparition, or if it occurred before the apparition because she had some unpopular position on something.
I would think the vitriol you perceive is merely criticism. Most normal people would not consider it bitter at all if you knew this "seer" as a poster over the years.
What has been lost, or not mentioned in these threads, is the absolute obnoxiousness of this person as a poster. On the old Angel Queen she managed to embed herself in with that very incestuous group that used to run roughshod over anyone who dared not see everything as they did. Back in the day at AQ, you could be in agreement with someone at a level of 99.9%. But that .1% difference would bring out the posse and before you knew it, you may say something that would get you banned.
Simple disagreements made politely, be myself and many others, were met by rude and nasty posts. And when you would get her in a corner and explain in a nice way how she wasn't necessarily right about something, a guy like gpmtrad would come around and work on you. So honestly, it was not all her fault. It was the nature of that board and I think she has a natural talent for manipulating others. And I mean natural as in garden variety. It wasn't based on any super intelligence or intellectual gifts.
She also monopolized the board and it was not uncommon for her to make 40 posts per day. Many of us eventually started referring to the board as the Dawn Marie Show. I honestly don't know where she got the time to be so active and still receive visions.
That triggers another thought. I always found it odd that so many women who claim to have large families and also homeschool have so much time for being busy bodies on forums. But that is just an aside. But a topic I have been meaning to broach for quite awhile.
