He said he's suspicious, but was not specific there. I've listened to a few of his videos now, and I can say he is soft spoken and generally avoids confrontation with his host. He seems honest, but also seems to prefer focus in on points of agreement between him and his host rather than points of disagreement. If this is simply following the same pattern as other presentations of his, it may be that he's just choosing his words well, ignoring those point of disagreement, and focusing on points of agreement. In this case, it happens to be suspicion, but he does not go much farther than that in his explanation.
