Long time ago a famous debunker wrote a book that listed frauds, fakes, and hoaxes. It was in alphabetical order. I got half way through the book, to the alphabet P, when I decided to stop right there and threw the book into the garbage bin. I stopped because "what else in the book may be true but betrayed as false. The debunker said that the Platypus was an Australian hoax. Well, I can tell you the Platypus is real and we, in the Northern Rivers of Australia, have plenty of them. It only took one false claim for me to not trust this debunker.
It would be funny if the book was not really written by the debunker. If so, then the book itself would be a fraud, fake and a hoax in itself.
The sad thing about all this trusting bit is that it can only take one lie to not be trusted; and can at times take a lifetime to regain that trust, if at all. I saw a lot of this in family breakups due to broken promises of giving up drug addictions, alcoholism, and gambling. The best a recovery person can do is stay true, and let time be the healer.
