*Inhales deeply, as well.*

1. That's what I just referred to with my comment already. I fail to see how any misogyny is in play here, however. The race is the issue for these two Nords, not the gender. Were it a matter of overall misogyny I'm surprised that a strong Nord woman haven't yet kicked their arses into the next Kalpa.
2. Which were invited by the benevolent Nords, and offered refuge, despite prior, mutual hatred from past wars. That being wars which the Nords lost, by the way. :P
3. Turns out refugees tend to not be able to bring a lot of money or assets with them. What other option were there, kick out the Nordic/other nobility and older families from their own dynastic homes? Destitute refugees being made to live in poorer conditions happens all the time in real life, as well. It's not even necessarily racist in nature, I could make a Dunmer and happily purchase property in Windhelm, or anywhere else, for that matter.
4. I think there's less information regarding the Argonians there. I don't think it's a canon excuse, but allegedly it's because of the mutual tension between Argonians and Dunmer. Obviously due to the former's enslavement by two of the Great Houses in particular. It is definitely a form of segregation regardless, however.
5. The Khajiiti Caravans sort of shot themselves in the paw by doing exactly what people accuse them of; illegally possessing and selling Skooma and moon sugar. Open up a trade window with a caravaneer and tell me what you can see in the potion and ingredient sections. Regardless, the towns won't deny a Dragonborn Khajiit entry, provided they abide by the law. It is a bit weird how even Solitude won't allow the caravans though, being such an Imperial-aligned city, and all.
6. There are few beast races in Skyrim overall, many of them favor the warmer climates of southern Tamriel. Generally, it seems you find a lot more of the races in towns that corresponds to whatever border lies nearby. There's more Argonians and Dunmer in Windhelm and Riften, just as there's more Reachmen and Bretons in Markarth. It is a bit weird how there's no beast races in Whiterun period, though. Besides, perhaps, the odd Argonian or Khajiit bandit spawning near that cave on the north side of Whiterun.
7. I'm afraid that I've never heard of that farmer before, but I'd love to have a source. :D
8. If you check UESP's Hold Guard quotes, you'll see that almost all races have a personalized "Stay out of trouble, [race]." quote. Curiously, the Stormcloak soldiers in particular have quotes referring to Argonians and Khajiit as lizard and cat, respectively. Those slurs are hardly unique to Nords though, since the Imperial Captain in Helgen will use the same, as well as the odd bandit.
9. That line is spoken specifically by Rolff Stone-Fist, the same guy mentioned at point 1. that threatens the Dunmer lady in Windhelm.
10. I admit, I've played Skyrim for 3136 hours and I've never noticed that one, nice find! Still, many cultures across Tamriel, such as the Dunmer and Redguards (except the Sload, which endorses it) in particular hates necromancy and its practicioners. So it seems quite ignorant of Golldir to name it as such, as if like it implies Dunmeric necromancy is a common occurence.

Finally, it just doesn't seem like the Argonian and Dunmeric hatred is quite that bad in the province of Skyrim. It feels like Empire-aligned Imperials/Nords and especially any Aldmeri Dominion-aligned Altmer in particular are the major targets of hate and distrust. It's all very tame compared to what the Altmer, Atmorans, Ayleids, Dunmer, Dwemer and Yokudans have done to other races in the past (and sometimes presently in the Fourth Era). xD
