Interesting enough there was no behavior described. It was merely a wholesale opinion, which perfectly describes propaganda. If he sincerely likes the guy, that's ok too. It just seems like he was ignoring the facts in favor of some type of bias adoration.

It would be interesting to know his opinion if she, after talking to Tom, still feels the same or worse. Will his opinion suggest that she is delusional or lying or would some godly doubt raise in his mind.

Those are my thoughts. He is entitled to blindly love anyone he wants to. I do not think that of itself is a bad thing. I simply thought that his bias analysis of the situation was very interesting.
