There's so much player-excreted shit that is just badly-camouflaged racism from typically the whitest motherfuckers in the community. Kender, Halflings, Tieflings, Goblins, Orcs, and Drow hate especially. That's part of my intensive vetting process anymore-- I gotta find out how the GM and players at the table feel about those races, and find out if there's already table in-jokes that sum up to applying real-world prejudices to fictional species. If there is, I can't be there; and it'd gall you to find out just how many tables I've walked away from for one instance of what I'm talkin bout occurring at that table.
