You called out something about the CBSRMT and Marshall's comments. He (via the writers) tried to EDUCATE the listener, not INDOCTRINATE them. Sure, there were exceptions. But try finding facts like this today on a network-produced TV or radio show (even, say, on a supernatural episode, at the end of "Carmilla", when Marshall described in gory detail what one was REALLY supposed to do with the corpse (and disposal) of a vampire according to eastern European legend).
