This is key comment of his review: " and deft not the type to fall into a "cult type" group."
So he views himself as not the type to fall into a cult type group as we all did.
He is being honeymooned and doesn't want to see it. The trap doesn't go off UNTIL you are in it.
This is the way it almost always is with these study's and I've seen quite a few. They all say the same thing because they are getting attention and don't want to believe that will go away. They don't realize what will happen to them. I am not saying the individuals who are studying with him are bad people but that doesn't matter. The cult is a machine.
