Oh, I love it when people bend over backward to deny institutional racism in fictional setting, as if it's a personal attack on their own honor. Ulfric Stormcloak is a power-hungry, glory hounding RACIST, and that's supported directly by all the lovely lore everyone with sense has been referencing. There is not a single redeeming quality to the man, unless you count aimless tenacity, which only counts if it's not aimed toward entirely selfish goals. But his army wears blue, so that makes him the Good Guy, I guess.
