Seriously, why the virtual racism?!
Imagine you're an ADD kid who just got that "super [censored] awesome game with sweet kill animations", Skyrim.
You want to get into it and start killing [censored] with an axe, but you start in some "gay-ass" cart and have to listen to some "[censored]" talk for "like, twenty minutes". Well at least the graphics are nice.
So you finally get off the cart and, not wanting to waste any more of your precious time, you just skip character creation alltogether. And because the game defaults to a Nord, you end up as a Nord.
