I have no doubt that if he appeared on the Paracast, he would be treated with respect befitting his own demeanour - that is, he seems a gent and should be treated as such. At the same time, it would be fair game to ask about his beliefs regarding the subject matter on C2C and for all we know, he may have a perfectly good response to any question about his interviewing style!
Without ever having heard his show, I'm guessing that he might say he does not confront and critique the claims of his guests because he seeks to encourage as many people as possible to report what they've experienced or to express their theories. That would be a reasonable approach, as far as I can see, since the subjects of ufos and the paranormal have been so widely shouted down in the past. I think it's why many people interested in these subjects today have to research these subjects extensively to find out what has been reported and hypothesized in the past.
