Albus Dumbledore, a "mudwallower"

Mudwallower is an incredibly insulting term for "Muggle-lovers." A good example is Albus Dumbledore, a headmaster of Hogwarts School of Witchcraft and Wizardry. Dumbledore championed the rights of Muggles and cherished the equality of Muggle-borns in the wizarding world. This strong belief earned him the derision of prejudiced pure-bloods, who believe that Muggles and Muggle-borns are their inferiors.
