In the Warhammer Fantasy novels there is plenty of xenophobia - being born with heterochromia (eyes with two different colours) might be enough to attract the interest of the Witch Hunters. During the orchestrated "Lahmian Uprising", many women were burned at the stake just because they had pale skin (so they were suspected of being vampires). Yet I can't recall any widespread hate towards non-humans: elves, dwarves, halflings or occasional ogre that live within the human lands.
I don't mean that all non-humans are generally loved - there might be occasional tension and unfriendliness against individual characters (because the given elf is pompous, that dwarf is rude etc), but I can't recall any situation where mob/hunters would go against non-humans specifically only because they are different ("The crops have failed it's the elves fault!").
So are they any Witcher-style pogroms anywhere within Old World?
