Yeah, I know. Sorry. But, hey, Robin HAS been given the opportunity to listen and comprehend, and she continues to imply everyone is too dense to comprehend the magicalness of JE. It's inaccurate, rude, and tiresome, and I reacted to that. I do that.
And I was kidding. These "hits" by JE are laughable.
Assuming we can take Robin's posts at face value (for a skeptic forum this is a hypothetical), I find myself wondering why her conviction appears to become stronger and more strident the more weaknesses are pointed out in what this conviction is based on. The underlying evidence remains unchanged, and the weight of argument against her interpretation has increased significantly since the start of the thread.
I suggest it's a question of emotional commitment, a variation of the 'Sunk Cost' fallacy with an admix of human pride. If she were to admit the possibility that JE is a fraud and was cold or warm reading her, it would mean not only that there were no vague messages from a deceased loved one, or that she was royally duped, but also that she couldn't see it despite months of painstaking explanation from people who are very familiar with frauds like this.
She has simply too much emotional investment to admit she could be wrong at this point, and the longer it continues, the more she will have to lose, the less she will be prepared to contemplate the probability she's been fooled by a mediocre stage act, and the more she will attempt to reinforce her belief.
I suspect that if JE were to be convincingly shown to be a fraud tomorrow (e.g. he or an aide is recorded admitting it, or he's shown to be taking instruction via radio, etc), Robin will continue to believe that the 'readings' she personally experienced and that her friends got from JE were somehow the 'real thing' - perhaps he tragically lost his powers afterwards, or it was a little splash of magic just for them, or he was caught taking a rest from psychic stress and didn't want to let people down.
Many people have this kind of emotional commitment to beliefs that seem absurd to the disinterested observer; humans seem wired to work this way, which gives frauds and charlatans an easy living. Skeptics make it their business to become familiar with the patterns of these scams, which makes it hard for them to see why others fall for them so frequently, but most people are unaware of the fallibility of their perception and recall and how easily they are manipulated.
In summary - I don't think there's any chance in the short term that Robin will be able to recognise or admit to being duped, but in the very long term our contrary opinion may have sown a seed of doubt.
