If the audience doesn't hear the author's intended message, doesn't that make him or her a pretty crap author?
ISTM that would rather depend on how subtle the author intended to be with the message. Certainly there might be cases where the message wasn't intended to be heard on a rational level, but only vaguely felt; this would seem to be a practical approach if the author expects his message to be less than palatable if overtly apparent.
