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.

Famous quotes containing the words blood and/or purity:
“It is a strange, strange fate, and now, as I stand face to face with death I feel just as if they were going to kill a boy. For I feel like a boy—and my hands so free from blood and my heart always so compassionate and pitiful that I cannot comprehend how anyone wants to hang me.”
—Roger Casement (1864–1916)
“Who knows what sort of life would result if we attained to purity? If I knew so wise a man as could teach me purity I would go to seek him forthwith.”
—Henry David Thoreau (1817–1862)
