I debated turning this question into a whole thread with a poll, but a sticker poll here should suffice.
Who are the real niggers of Tamriel? Vote with stickers.

- Redguards, they look like, and sound like, real world niggers, but does that make them the niggers of Tamriel?

- Orcs, they are violent and primitive barbarians, and they had to struggle to be recognized an equal/legitimate race.

- Beast Races (Argonians, Khajiit, and Imga), sentient animals, often enslaved and used as farm equipment, the Imga are gorilla people from lore, added to Morrowind by Tamriel Rebuilt.
