I agree about the seemingly one race rules all attitude put off by Nords. Only, in a world of millions of races, we do the same. There's nothing wrong with a 'we are the best' outlook. It's close-minded, but understandable. When I first played Skyrim, Ulfric seemed to be more of a power hungry dictator rather than dedicated freedom fighter. The way he speaks to everyone in the game only solidifies my mindset. (Note: You all know we can sit and listen as a third party to any Skyrim characters' conversations)
I don't think most players bother to read about who Tiber Septim was or what he did. They're like Shor and carry this picture of an amazing hero-god who founded an empire, disregarding the vast swathes of death and destruction he unleashed on anyone who didn't kiss his feet.
Mention he was Dragonborn and they gasp with "Ooohs" and "Aaahs", and say, well he must've been blessed by the gods.
