leaning, present within the skinhead movement since the late 1960s, became progressively dominant in the United Kingdom, fuelled by the job crisis, the economic decline, and an increase in immigration during the late 1970s–early 1980s. By the early 1980s, the white power skinhead subculture had spread across most of Britain, largely "through face to face interaction among the fans at football matches." The cartoon character Black Rat, created in 1970 by French artist Jack Marchal, was adopted by young neo-Fascists in various European nations and became an essential marker of the fringe culture. Music played a key symbolic role in the political polarization of the skinhead subculture. Marchal recorded a French Hard Rock album named Science & Violence in 1979, and German students of the neo-Nazi party NPD formed the first German nationalist rock group in 1977. A new music genre, Oi! – a contraction of "Hey, you!" pronounced with a Cockney accent – emerged as a skinhead version of punk rock in the late 1970s, contrasting with the sometimes multiracial bands of the left-wing and unpolitical skinhead resurgence, which rather drew influence from the original Jamaican Ska roots of the late 1960s. Coined as a nickname for the new genre by British journalist Gary Bushell in 1980, "Oi!" soon became synonymous with "skinhead". Unlike many of their followers, however, early Oi! band members were generally not neo-Nazi or even affiliated with right-wing organizations, and they increasingly distanced themselves from some of their fans, who contributed to recurrent riots at concerts. In July 1981, the "Southall riots" were sparked when hundreds of skinheads were welcomed at an Oi! gig which was performed in a predominantly-Asian suburb of London. Some skinheads began to attack the neighboring Asian stores, and 400 Asians later responded by burning the venue with paraffin bombs while the skinheads were fleeing with help from the police. The event led to a moral panic in Britain and the skinhead subculture was firmly associated with right-wing politics and "white power music" in the public's opinion by 1982. According to Brown, some lyrical themes of Oi!, such as social frustrations, political repression and working-class pride, were common to other genres such as country music or blues, but others like violence ("Aggro", for 'aggressiveness') and football hooliganism "could be easily interpreted in extreme right-wing terms." The phrase "all cops are bastards" was popularized among some skinheads by the Oi! band The
