Nords(Stormcloaks) aren't racist against the dark elves, it's just that those dark elves openly support the empire, and demand that Ulfric devert resources from the war to help them.

The Gray-Manes are really the best example of Stormcloak supporters(and their goals), they're not racist themselves, but they want the Nords to rule Skyrim, they value honor and familly above all else, and they are willing to put their own lives on the line for what they believe is right.
