I'm a full scale pilot too. I fly with my left hand on the wheel because my right is on the throttles in most planes. When I fly from the right seat the situation is reversed. When I fly a Pitts though I fly with my right hand on the stick and left is on the throttle. It's called "adapting" to conditions.

If you "choose" not to do so, that is your "choice". A case of being stubborn IMO. No insult intended.
