It's clear that you disagree with me.  That's fine.  
But I honestly don't get your point.  
The messages about which you are writing are delivered as part of the appearance.  If the appearance did not really happen, then neither was the message given.  I don't understand how anyone other than the one who was the recipient of the vision and message can know for certain if it occurred.  One can choose to believe, but one cannot know.  The institutional Church can choose to designate certain visions and messages as being legitimate and others not, but I find the exercise pointless.  
There is no reason that you need to agree with me, but in all that you have written, I have found no basis for your perspective, other than personal opinion, just like mine.
