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

You basically called her stupid/slow/retarded for enjoying repetition more than you do. The average person would think that's rude.

i didn't call anyone stupid or slow. Someone with autism might be fascinated by something i would find simple and pointless for hours, but that doesn't make them stupid or slow, or me smarter. It means they experience the thing in a different way than I do.
