Why is race and nationality ignored so much in the lore? (why does the lore fail)

[Gramul]

If you enjoy meaninglessly sitting in front of a computer and walking through repetitive terrain over and over again it probably means your brain didn't properly develop or you have some sort of mental difference from the average person like an autism spectrum disorder or OCD.
Or you are just a very boring person with a lack of a drive to do anything useful

Rude.

note: everything i said here is -very- simplified so don't take it the wrong way.

Oh, well I guess that makes it OK.
