I find the attitudes of people in the forbidden west very interesting.
Going into the forbidden west we are told that the tenakth do not get along whatsoever with the carja or anyone else from the east. Which obviously figures because of the red raids. However when we first arrive in scalding spear, or thornmarsh, or any of the other small tenakth settlements, we are welcomed by basically everyone. The exception to this is the bulwark, but that's only because they hate everyone, not just the people from the east. (And of course there are the rebels)
Meanwhile, when we arrive in stones echo (an utaru village) we are met with: "keep out outlander, stones echo is utaru only!"
I find it interesting that the utaru throughout the game are so inherently racist/xenophobic towards:*literally everyone* and even the Quen arnt much better. The utaru are supposed to be relatively chill with the carja by now, so why are they so hostile whilst the tenakth (who are supposed to be hostile) are chill?
