who are not of Germanic origin but have Nordic characteristics such as blonde/red hair and blue/green/gray eyes, were considered to be a Nordic admixture and suitable for Aryanization. In the United States, the groups most associated with the white supremacist movement are the Ku Klux Klan (KKK), Aryan Nations, and the White American Resistance movement, all of which are also considered to be antisemitic. The Proud Boys, despite claiming non-association with white supremacy, have been described in academic contexts as being such. Many white supremacist groups are based on the concept of preserving genetic purity, and do not focus solely on discrimination based on skin color. The KKK's reasons for supporting racial segregation are not primarily based on religious ideals, but some Klan groups are openly Protestant. The 1915 silent drama film The Birth of a Nation followed the rising racial, economic, political, and geographic tensions leading up to the Emancipation Proclamation and the Southern Reconstruction era that was the genesis of the Ku Klux Klan. Nazi Germany promulgated white supremacy based on the belief that the Aryan race, or the Germans, were the master race. It was combined with a eugenics programme that aimed for racial hygiene through compulsory sterilization of sick individuals and extermination of Untermenschen ("subhumans"): Slavs, Jews and Romani, which eventually culminated in the Holocaust. Christian Identity is another movement closely tied to white supremacy. Some white supremacists identify themselves as Odinists, although many Odinists reject white supremacy. Some white supremacist groups, such as the South African Boeremag, conflate elements of Christianity and Odinism. Creativity (formerly known as "The World Church of the Creator") is atheistic and it denounces Christianity and other theistic religions. Aside from this, its ideology is similar to that of many Christian Identity groups because it believes in the antisemitic conspiracy theory that there is a "Jewish conspiracy" in control of governments, the banking industry and the media. Matthew F. Hale, founder of the World Church of the Creator, has published articles stating that all races other than white are "mud races", which is what the group's religion teaches. The white supremacist ideology has become associated with a racist faction of the skinhead subculture, despite the fact that when the skinhead culture first developed in the United Kingdom in the late 1960s, it was heavily influenced by black fashions and music, especially Jamaican reggae and ska, and African American soul music.
