Why are you diminishing her accomplishments?
Never mind that the series is full of people seeking control of the North.
Am I? I thought I was being fair. Being Queen in the North is essentially being the handsomest Denny's waiter.
As I understand it, controlling the north is basically herding cats. It needs to be controlled, otherwise it diminishes the stature of the Iron Throne, but for political purposes, it is largely left alone, which is how it has operated and why no one on the new council really cares when Sansa defies them on it. Another group, King or Queen, less familiar with Sansa, would probably not allow it unless they were politically weak, or unwilling to go to war in the short term.
Also, Arya did some things. Brienne too.
Really nothing taken seriously in a standard Western ideology says women can't "do some things." But they don't usually end up as the most powerful political person. Usually.
