What you're saying and what I'm saying are not mutually exclusive. Authenticity should always be a goal. Belief in one's own words, likewise, is a solid precondition to success. All of these things are factors in success, as is knowing the audience. It's possible to make a successful speech without achieving any or all of these factors, but achieving them makes success much more likely. It makes the delivery of the speech less of a dice roll.

I didn't mean to suggest a reductionism in favor of one factor over all others; I was simply replying to a statement in the grandparent comment about the relationship between audience and speaker. (Also, I'm not suggesting that one should pander to his audience).

That's fair enough.
