"I have never been able to play as a true Nord. When I do, I feel I have to side with the Stormcloaks and while I respect them, I can’t even finish the attack on Whiterun."

What a true Nord means to be is arguable. Many would say that loyalty to the Empire is a required prerequisite as Nords have always have been fanatically loyal to it (thus why all those forts were in disrepair and not manned until you go deep into CW quest-line: there was no need for ‘em).
Talos? Any Nord from 200 years ago would be disappointed to see Talos worshiped as a god XD (no seriously, they worshiped him but as a hero, which sometimes put the Nords at ods with Imperials who worshiped him as a god). It could be even argued that a True Nord would not worship the Divines but the traditional Nordic pantheon.
