Odd that people take offence at the patriotism of the Nords (and call it racism), while the Thalmor are self-avowed racial supremacists and religious bigots, with the Empire as their Vichy government.
The cause of Ulfric and his Stormcloaks seems just and legitmate, even by our modern standards: Nord self-determination and struggle against rleigious intolerance.
I don't take refusing to treat Dunmer as equals and refusing Khajitt and Argonians the right to enter or live in their cities, and I don't see how calling the Nords racist is saying the Thalmor aren't???
Their main goal may be just (Talos worship) but Ulfric still wants to exile all other races based on the Empires behaviour, which is racist.
