Xenophobia, yes - there's a great deal of antagonism toward the vane and other nonhuman races due to the civil wars. And of course a public perception that everyone from Jorat's... we'll say, "provincial". The only people I'd call truly white are those from Doltari - and Senera's never mentioned being judged for that or having a position of power of anything due to it. Although Quur's no paradise; there's a never-ending fountain of misogyny and homophobia, though thankfully both appear to be on the way out as more progressive areas of the empire mingle with the central towns.
At any rate - the ignorant are unfortunately everywhere, and sometimes the only antidote is good friends.
