I’d you get to a point where you feel like the author is just destroying the credibility of Dr. John Mack, I would suggest to just keep going.
I was almost getting angry at one or two points during this but I kept going to finish it and it turned out to be pretty great.
I would say that my view on Dr. Mack has changed however. He had some issues regardless of his amazing credentials. I don’t know how to quantify that yet.
