Lookism: prejudice based on appearances. Generally, pretty people good, ugly people bad.
Faithism: prejudice based on religion. Generally, Christian good, others bad; sometimes Christian-with-agnostic-leanings good; any strong faith bad.
Linguism: prejudice based on language. English good; everything else bad.
Disablism, sometimes just Ablism: prejudice based on physical/cognitive abilities & differences. Easy to use as a template for Wizard/Muggle situations.
Housism: unique to the Potterverse; anti-Slytherin sentiments.
Speciesism: Originally used in the Pratchett books. Prejudice based on "race" as exists in scifi/fantasy books, rather than human skin color & cultural background. Umbridge is a speciesist. (Yes, it's a ridiculous-sounding word. It's Pratchett; I'm surprised it flows as well as it does. Suggestions for alternatives are welcome.)
