With the possible exception of Bretons or Imperials (humans) who are married to Nordics, everyone else shouldn't even be in Skyrim. They simply do not belong here and should be forcibly removed or dealt with by other methods and their property seized. Their presence threatens Nordic safety, security, and prosperity and they don't worship Talos. Even if we don't go that far non-humans obviously absolutely cannot be tolerated in Skyrim. They are barely human (well actually not human at all) and completely alien threat to all men. I don't think any of us even wants to even IMAGINE the POSSIBILITY of inter-species birth between those cat-monsters and lizard-creatures and Nord women. Nords should be humanists.
Ulfric was a visionary when he hinted towards the pure Nordic policy in the storyline but I think its completely logically to go to the next step. There is a simple solution - maybe a final solution - and that's to remove all non-Nordics from Skyrim or if they refuse to leave deal with them appropriately. Multiculturalism is what destroyed the Empire, the Empire tolerates all forms of disgusting completely inhuman races doing trade and some even FIGHT for them. That is why the decadent disgraceful degenerate Empire lost against the Mer and is corrupt and collapsing all around as it feeds on itself.
Do we really want that to happen to Skyrim? Do you really want your Nordic daughters or sons having relationships with sub-human non-human species? Do you really want these aliens and imperial sympathizers undermining our freedoms and plotting against us?
What do you proud Nordic men of Skyrim say? Who is with me? Hail Ulfric! Hail Skyrim!
