So if a Nord says "Those damned Nords that support the empire should beaten" Is he now racist against himself?
He's being derogatory to that particular group.
It's about context.
The game lore, and story of Skyrim, clearly paints a rift between races, namely the Nords and the Elves, especially the High Elves. Nords have little, if any, love for Elves and High Elves look at Nords as beneath them.
Saying things like "oh great,
another Dark Elf," is not a nationalist thing, it's a race issue.
All the races think they're superior to the others. This is just the normal MO in Tamriel.
What people are looking for is some indication that the Nords are extremist, and for the most part they're not. If they were as racist as they're made out to be in the forum and elsewhere on the internet, they'd have never let the Dunmer settle en masse with such generous terms, or let the strongholds exist peacefully.
The OP found out that the treatment of Argonians in Windhelm is just old fashioned greed, not some fanatical hatred for Argonians. But apparently that's disappointing to some people?
Except you can be a passive-aggressive racist.
Why, exactly, is the Grey Quarter a slum?
