Blood traitor



"Blood traitor" is a derogatory term commonly used by elite pure-blood families to describe witches or wizards who sympathise with the non-magical community and/or willingly associate with other such sympathisers or with Muggle-borns. Other similar terms include "Muggle-lover", "Mudblood-lover" , "Dunglicker", "Scumsucker", as well as "Mudwallower" , all of which refer disparagingly to those who are comfortable in the company of Muggles and/or Muggle-borns, whom prejudiced wizards and witches believe are dirty and inferior. The most notorious blood-traitor family was the Weasleys.

 * Pure-bloods who marry Muggle-borns or Muggles
 * Pure- or half-bloods who oppose prejudice based on blood purity
 * Pure- or half-bloods who openly agree to equal rights for Muggles and Muggle-borns

Attitude towards "blood traitors"
Most pure-blood wizards and witches consider themselves to be the elite of the wizarding world, akin to royalty. They look down upon half-bloods, Muggle-borns and half-breeds, as well as consider the Muggle world to be inferior to their own. Pure-bloods, as well as even half-bloods, who do not share this view are considered traitors to their own kind, hence the term "blood traitor". They are considered disgraces by pure-blood supremacists such as the Malfoys.

Elitist pure-bloods believe that it is a sign of weak magic to enjoy non-magical company, as well as seem to believe that some of the supposed dirtiness of Muggles and Muggle-borns will rub off on those who associate with them, thus they consider blood traitors to be "filthy" as well.

Some extremists consider blood traitors to be nearly as bad as the Muggle-borns they are prejudiced against. Bellatrix Lestrange, for example, claimed that "blood traitor is next to Mudblood in [her] book", as well as her family often disowned and blasted off the family tree any members who could be considered blood traitors. Blood traitors might also be shunned by their families and acquaintances: for example, Bellatrix and her younger sister Narcissa Malfoy stopped seeing their sister Andromeda after she married a Muggle-born wizard, Ted Tonks.

Lord Voldemort and his Death Eaters targeted blood traitors during the First and Second Wizarding Wars because they opposed their goals. When they were temporarily in control of the Ministry of Magic in late 1997 and early 1998, they kept blood traitors such as Arthur Weasley under surveillance. However, even most Death Eaters were reluctant to kill pure-bloods, even "traitorous" ones, if it could be avoided. The same situation existed at Hogwarts School of Witchcraft and Wizardry while Voldemort was in power.
