I think skinhead is synonymous with white supremacist in America, but in the UK for extended periods of time Skinheads were just kids who wore a certain type of clothes, and listened to music(originally by, or from, the West Indies). A lot of the people in this counterculture were Black and mixed. This "anti establishment" culture was taken by a lot of white supremacist, but also antifa, groups as well. There isn't a club around that didnt have supporters, in some form or fashion, who was not following this subculture in one way or another.
