I think you're missing the most powerful techniques - those that distort language. Whether it's euphemism that distorts, as identified by Orwell, or intensional language as identified by Korzybski, that communicates no actual facts, but allows the listener to fill in the blanks themselves.

And I disagree with the walking bit. Like the Sundance Kid, I'm better when I move. (Obscure reference to Butch Cassidy and the Sundance Kid. Never you mind.)
