Unless this mod adds the N word, t’s really not. There’s a lot of racism in the elders scrolls universes that is there for worldbuilding as opposed to thinly-veiled stereotypes of real races like in Harry Potter*. Pretty much every race has issues with the others just like they would in the real life equivalent of the time period.

It’s not at all the same as other mods which add real world bigotry into the game

*One could argue that Khajiits are analogous to the Romani people but it’s a stretch
