Pretty much universally the dialog is written this way, I stopped getting invested in it very early on. You have control over what your character does but none at all on how he acts. Put it down to royal upbringing but he is always diplomatic in agreeing with people and never asks for clarification.
Now that I think of it the dialog for the commander is much better written than I gave credit for, if you think about what kind of a character he would be it makes a lot of sense. He doesn't respect Scarlett enough to discuss her views, if he agrees with them he'll pretend to go along, if he doesn't then his opinion is law and that's the end of it.
