You Imperial Milkdrinker! Everyone knows the Nords should rule Skyrim!
I'm a Breton, so for all I care the Nords can go back to pretending they're the cool viking warriors, as long as they do their job of defending the northern imperial border instead of bickering amongst themselves.
Besides, I don't trust Ulfric, and the Thalmor quest puts even more doubt on his role.
