The Church has always held the vast majority or Marian apparitions to be either fake or daemonic. That is why the Church always conducts a very thorough examination before declaring an apparition to be "worthy of belief" (post-Apostolic revelations are never a requirement of belief).
What evidence do you have to prove the Fatima apparitions daemonic?
I think there’s some links or some such on my FR home page.
You can search Amazon.com for some Portugese researchers’ books on the topic.
They were very thoroughly and methodically researched . . . primary source materials from the time—the local Church even opened it’s secret files on it all for them. And, they interviewed survivors still alive at the time of their writing.
The nuts and bolts of it is not really a topic that I’m allowed to discuss any more on FR.
It will take some time yet for the truth to be faced.
