You mistake my logic yet again. I didn't say more diverse equals more racial tension. I said saying there's equality in a place with low diversity is a piss poor argument.
Riften I like because its a good example of that racism for stormcloaks argument being bs. Riften isn't the same because it isn't home to a bigger population, so there was never a segregation law placed, and the Dunmer there seem to get that work without complaining = local respect. As said by Tdroid's source.
And for whatever reason, they get along unlike in Windhelm, where argonians and dunmer apparently dont:

And if what Ulfric did wasn't smart, why did the legion see fit to also send troops in search of the Jagged Crown? It is a symbol to the Nord people. Killing Torygg with the thu'um and gaining the support of half of Skyrim shows how important symbols are.
