Dwarves are grudgingly admired for their work ethic, halflings and gnomes are treated with amiable contempt, and elves are not to be trusted.
Further to this, the stereotypes of races vary by village IMC. PCs are often surprised when they find that the Dragonborn is fine at one place, but the Dwarf is not. Here is some fun racism (not a term I have used before hehe) that I have used in the past:
Dwarfs
= They took our jobs! DEYTOOKOURJEEEERBZ!!! An ethnic minority that works harder than everybody else, makes a bit of money, and is then demonized as job stealing? Makes perfect sense to me
= Bankers who overtly/secretly control everything!
Gnomes
= DEYTOOKOURJEEERBZ!! Rock gnome engineers came in and automated the mill, putting half the locals out of business. You might be a forest gnome, but the luddite mob does not care about the difference.
= They are changelings, the elves steal children and turn them into fey. Gnomes are cursed stolen children who will never grow up. Everybody stares at them, trying to work out whose child they are. Often driven from town, or even murdered by drunks that would rather see a child dead than turned into a monster.
Dragonborn
= Are treated based entirely upon what the last Dragonborn through here was like. They tend to be heroes or villians, so its a toss up. Most people have only met 1 of them before, so whoever they have met before entirely dictates their generalizations.
= Greedy, come to take all of our gold and horde it
Elf
= Fine, but if a child goes missing, everybody knows the fey one stole it. If the milk curdles, you will be whipped out of town. Sometimes they get appeased, asked to give blessings to pregnant women, asked to preside at a harvest festival etc. Heaven help you if the last harvest failed.
Tiefling
= It is bad luck to outright hurt one, or refuse them the very basics of hospitality. It is also bad luck to invite them in too readily, share a meal with them, and 1000 other superstitions.
= Villagers wash hands with salt if they touch one. Tend to wear garlic necklaces with them around. Refuse to walk in their foot steps. Cross the street to avoid walking through their shadow.
Halfling
= The earnest belief that rubbing their tummies is good luck, leads to some very awkward social interactions.
= Halfling feat are exceptionally good luck, when buried in a field they will make the harvest grow plentifully. If placed under a marriage bed, the couple will have healthy children. Under a cot, the child will grow big and strong and free of disease. This leads to some pretty creepy scenes.
= Because their farms are better than human ones, they must have taken all the good land for themselves. Humans sometimes want to make mobs to take back some of this 'good land' for themselves.
