Blood Purity
The longstanding separation between the Wizarding and Muggle worlds in the Harry Potter universe has led to many wizards to advocate keeping the two apart. This view has in turn led to a minority of wizards seeing Muggles (and wizards of pure Muggle parentage) as untrustworthy, foolish, or, in extreme cases, racially inferior. The common practice of wizards marrying Muggles is viewed by such extremists as miscegenation, and they instead advocate maintaining a so-called "purity of blood." This was part of Lord Voldemort's ideology, and the Black family disowned anyone who married a half-blood or muggle. However, in Harry Potter and the Chamber of Secrets, Hagrid states that there are very few wizards who actually have blood purity.

“My death, taking the light from my eyes, gives back to the day the purity which they soiled.”
