Strawman.
Her inexperience at ruling has already been stated multiple times.
It's not a strawman, it's an if-then statement given the fact the topic of her inexperience was quickly dropped by people who seem keen to bash her support of the Empire. An if-then statement designed to allow those people to retract that as the thrust of their argument and substitute something else.
Her inexperience is a rather small issue given the fact she has advisors that can be trusted who have a lot of experience.
Several NPCs in the city mention that General Tullius has the real power in the situation. Of course Elisif is going to deny it. I don't WANT this to be true, because I actually like Elisif, and was sad when I saw what was going on. She is a better person than Ulfric is, but it doesn't amount to anything when she can't make her own decisions. Every single time she makes a decision in the game, her advisors step in and tell her she's wrong, and she changes it. Except when she appoints you Thane, which is just a title.
Let's be fair, the decisions she tries to make in those situations that are objected to ARE bad decisions. Her changing her mind when someone points that out is a good thing. Or is a leader supposed to stick with any decision they make, no matter how stupid?
Erikur is not a military leader: when he says it's Tullius in command, it's the city he's talking about. We never see Tullius make decisions, granted, but nor do we see Elisif.
We actually see Elisif make decisions, including but not limited to appointing Firebeard to handle certain problems.
Falk and Tullius support the empire, too, and I still say they're the power behind the throne.
Because Elisif WANTS them to be and given their experience and her inexperience, can we really say that's a bad decision on her part? Let's be clear though, it IS her decision. They don't coerce her into anything.
