venues and distributors has developed. Some punk bands have chosen to break from this independent system and work within the established system of major labels. The do it yourself (DIY) ideal is common in the punk scene, especially in terms of music recording and distribution, concert promotion, and photocopying magazines, posters and flyers. The expression DIY was coined by commentators after the fact. Specific ideologies and philosophies The following include some of the most common ideologies and philosophies within the punk subculture (in alphabetical order). Anarchism There is a complex and worldwide underground of punks committed to anarchism as a serious political ideology, sometimes termed "peace punks" or "anarcho-punks." While some well-known punk bands such as the Sex Pistols and The Exploited had songs about anarchy, notably the Pistols' "Anarchy in the UK", they did not embrace anarchism as a disciplined ideology. As such, these bands are not considered part of the anarcho-punk scene. Anarcho-punks typically believe in direct action. Many anarcho-punks are pacifists (e.g. Crass and Discharge) and therefore believe in using non-violent means of achieving their aims. These include peaceful protest, squatting, legal graffiti, culture jamming, ecotage, freeganism, boycotting, civil disobedience, hacktivism and subvertising. Some anarcho-punks believe that violence or property damage is an acceptable way of achieving social change (e.g. Conflict). This manifests itself as rioting, illegal graffiti, vandalism, wire cutting, hunt sabotage, participation in Class War-style activities, melee weapons and in extreme cases, bombings. Notable anarchist punk artists include: Aus-Rotten, Dave Insurgent, Crass, Subhumans (British band), Colin Jerwood, and Dave Dictor. Animal rights and veganism In the 1980s, both straight edge hardcore punk in the United States and anarcho-punk in the United Kingdom started to become associated with animal rights. This association was made possible through activism by bands such as Napalm Death, Icons of Filth, Conflict, and Electro Hippies. Some musicians in these bands were vegans and vegetarians themselves and publicly advocated for these ideologies. In addition to this, bands at the forefront of this movement included lyrical themes pertaining to animal rights, vegetarianism and veganism. Consequently, these ideas became a feature of the punk subculture and this association continues on into the 21st century. A notable example is Jack McGarry of the band SX-70 citing messages of animal rights in lyrics of music he listened to as an influence in becoming vegan. It is additionally evidenced by the prominence of vegan punk events such
