Sorry no - not saying that.
Ask yourself how you can have symmetric airfow around the fuselage when there is rudder applied.
If the airflow is symmetric then the rudder is central.
Think of the tail as a whole and imagine what happens when you wag the tail with the rudder!! Every wag results in a sideslip. If that doesn't compute nut out what happens when the captain of a ship commands "Right full rudder"
I feel a wag story coming on but will spare you!
Does that help?
