Sure, conversation is subject to rhetoric, but what I am saying is that you are able (insofar as you are capable) of trying to unravel the rhetoric, as the conversation involves you and another person. Thus, you have more power in conversation. Whereas, documentaries is more passive. But if you are referring to conversations that you are viewing as a passive observer, then I totally agree with you.

I can't speak for you but I think about what a documentary is showing me and consider it against what else I know, just like having a conversation with someone.
